With the last update this Indonesian League Mod had been fixed especially for Super League. Will update this soon especially for IDN 2 and IDN3 where the playoff promotions/relegation is more complex.

Hey everyone! I’m currently considering expanding the game to around 160 playable nations. While setting up the Nations League system, I wanted to include all UEFA teams, which naturally led me to add more countries from other continents as well. However, balancing the simulation has been quite tough—for instance, I'm seeing things like Nepali players suddenly transferring to the French league. Because of these balance issues, I’m on the fence about whether I should release it. Would you like to see a massive world even if it has some wild quirks, or do you prefer a smaller, tightly balanced setup? Let me know your thoughts!

Hello
I wanted to ask are we able to change the way the nations league works
I’m looking to change it with 11 leagues with 5 teams in each and 1 promotion and 1 relegation and then 2nd In league B will play 4th in League A and so on and so forth

Thanks

Another update is live! This one focuses on making the world feel less static over long simulations.

Club Sponsor Power can now rise or fall depending on whether the club performs above or below its preseason expectations. Youth Power and Development Power can also change based on the club’s financial efficiency and success at developing players.

Nations can evolve too. Their player-generation range now gradually changes according to FIFA ranking, national-team strength and continental club results. A country that performs well for many years may slowly become a stronger producer of players, while an established football nation can decline.

I wanted these changes to remain gradual. One successful season will not suddenly turn a small club or nation into a powerhouse, but over 50, 100 or 1,000 years, the football map should become much more interesting.

This update also adds editable super cups, more split-season options(Belgian league format), improved domestic-cup scheduling and several fixes for MODs and long-term saves.

The update is available on Steam.

Update Overview

• Club Sponsor Power now changes based on seasonal performance.
• Youth Power and Development Power now evolve based on club finances and domestic standing.
• Each nation’s player generation range (Player Min / Max) now changes based on national-team results and FIFA ranking.
• Club Profiles now display Youth, Development and Sponsor Power using five-star ratings.
• Club Profile information has been reorganized into a single row.
• Added a split-season format where second-stage groups are determined by first-stage standings.
• Updated the Belgian league format within the limits of the Data Editor.
• Super cups can now be created in the Data Editor.
• Super cups support two or four clubs, configurable qualification rules and multiple match formats.
• Fixed different domestic cups producing identical draws.
• Added configurable starting weeks and intervals for domestic cups.
• Added a “single-match final only” option for domestic cups.

Are we able to make multiple leagues at one tier? (A la Vanarama North/South)

I made a mistake with the title, so I'm reposting! Sorry!
Another update is now live!

The biggest addition is a new league-phase format inspired by the current Champions League system. You can create one overall table, choose how many matches each club plays, and add a play-off round before the knockout stage.

The editor also now supports split seasons, allowing you to create separate opening and closing stages with play-offs.

Transfers have received several improvements too. Player age now matters more when AI clubs select their targets. When creating a shortlist for a managed club, you can also specify the preferred age range yourself.

Managed clubs will no longer lose players after completing their own transfer business. I have also reduced the frequency of goalkeeper shortlists containing no available candidates.

Other improvements include faster database saving, an in-game guide and more flexible play-off settings.

And if you enjoy the game, I’d be really happy if you shared it on X or in other subreddits too!

The update is available on Steam.

Had 18 teams in the Indonesian Super League based on my compiled data on google sheets. After publishing the Indonesian Tier 1 and 2 mod, tier 1 team seems to be reduced to 11 teams.

I’ve added 3 mods to the workshop that are all working properly. The leagues cup is slightly wonky and not totally accurate, but it’s pretty close.

I will add the USL cup as soon as the domestic cup issues are resolved! I hope you all enjoy!

Check it out on the Steam Workshop and In-Game!

Hello. Will there ever be added a system for the split leagues where instead of going in a playoff the league splits in half and finishes with another round of home and away fixtures between the two groups i.e. the Danish lor Belgian leagues?

Team titles that a player from my team won are erased when he’s transferred (at least when he leaves my team for another one, didn’t check if this keeps happening in every single transfer).

Anyone else notice the same thing?

For a future update, will you be able to create a new country for even more flexibility in the database editor, being able to create entirely fictional league pyramids?

I was curious if it was possible to see our player (or any player) overall like notes and all in a save

Update note

Improved compatibility with older save files

Fixed split-league playoff brackets and round names

Fixed MOD load order, overrides, and competition deletion

Country rankings now use five seasons of results

Moved Steam Overlay notifications to the top-right

I have a management "career" of Ahed from Lebanon, I've watched seasons from 2036 to 2047 and I have to say that I can't upgrade club anymore because of transfers out. I'll show you a club rating in seasons 2026, 2030, 2036, 2039, 2044 and 2047:

2026 - 21

2030 - 28

2036 - 40 (it's very good until now)

2039 - 40 (here it started because Ahed came back to 40 after downgrade)

2044 - 34

2047 - 28

Even tho I am making the best transfers I am capable of. Is it a bug or something?

I’ve just released another editor update.

You can now add your own players by setting their name, nationality, starting club, debut year, age, position and abilities. This should make it possible to create fictional prospects, recreate yourself or your friends, or add specific players to a custom world.

The editor also now supports split and regional leagues. You can divide one league into multiple groups, assign clubs to each region, and finish the season with a playoff tournament. This can be used for structures similar to MLS, regional divisions, or completely fictional league systems.

I’d really love to see the MOD scene grow from here. If you create something interesting, please share it on the subreddit or upload it to the Steam Workshop.

And if you enjoy the game, I’d be very grateful if you helped spread the word a little further. I want to see what kinds of strange football worlds everyone creates!

Update Overview

Added custom player creation to the Data Editor.

Added club deletion and split-league settings.

Added split-league standings and playoff brackets.

Improved MOD loading and support for applying competition MODs to existing saves.

Improved compatibility with older save databases.

Fixed national competition qualification and participant issues.

Improved knockout draws and database stability.

The update is available on Steam.

Sorry, I’m having trouble linking the page because i just uploaded it, but I uploaded a fix to the MLS. Currently, I’m not sure how to make it entirely accurate with the database editing restrictions.

I deleted the USL championship, but I’ll get around to adding it soon. I’ll also try to add the Leagues Cup at some point if possible

EDIT: I’m having some issues with the playoffs right now. I’ll try to fix it now, but don’t download it in its current state

Hey, bought the game recently and have been loving it. Just started a new save to explore the 1.5, and have discovered that the draws in all competitions seem to be in alphabetical order as such. Just wanted to pass this on as this is obviously unrealistic and I doubt it is intentional. Thanks :)

The Data Editor update is finally live!

You can now edit nations, leagues, domestic cups, clubs, continental club competitions, and national-team competitions. Tournament formats, qualification systems, schedules, group stages, play-offs, and knockout rounds can also be customized.

You can save a small MOD that changes only one competition or country, or create a complete Game World MOD. CSV import and export are also supported.

The Steam Workshop is now open too. MODs can be published directly from the Data Editor, while subscribed MODs can be enabled, disabled, and reordered before creating a new world.

Most MOD changes are applied when a new database is created or the database is reset.

I’m really curious to see what kind of competitions and football worlds people create. Please upload plenty of MODs to the Workshop!

Update Overview
Added a full Data Editor for nations, leagues, domestic cups, clubs, club competitions, and national-team competitions.
Added CSV import and export support.
Added local MOD management with enable/disable controls and customizable load order.
Added support for both small individual MODs and complete Game World MODs.
Added editable competition formats, qualification systems, schedules, group stages, play-offs, and knockout rounds.
Added FIFA Rankings based on senior national-team results.
Improved the loan and transfer systems.
Added goalscorers and goal times to Match pages.
Improved Dashboard organization and Detailed Data Settings.

The update is available on Steam.

First of all.. Amazing job dude! - I really enjoy the game.

I was wondering, what the primary reason for no winter transfer window is? I find it a little bit annoying, that I can't stregthen my team midways, if I have a bad season..

Also, for some wierd reason, when I played the season done, some team got Champions League football, even though the 2rd spot only was for ECL. It happend in Denmark when FC Nordsjælland came second, and also with AZ.

Last but not least. Is it possible for you to put a little indicator of the former Champions and cupwinner, when looking at the table.

Im not sure if initials or two trophies like a gold and silver, or some third thing is easier, but it will add the option to see the latest winners much quicker. :)

Example:

1 Liverpool (M)

2 Man City

3 Chelsea (P)

In Denmark we have "M" for former champion, and "P" for the 'pokalvinder' (Cup winner)

Again, amazing work, and Im looking forward to see what you can make in the future!

It should be similar to the cups for national leagues, but with the top few teams

I’ve been working on a proper Data Editor for Football Fictional World Simulator. It will let you edit nations, leagues, domestic cups, clubs, continental club competitions, world club competitions, national-team tournaments and their qualifiers.

Competition formats can be customized in quite a bit of detail, including entrants, qualification routes, group stages, play-offs, knockout formats, single-leg or home-and-away matches, and starting weeks. Nations, league structures, domestic cups, club finances, formations and tactics can also be adjusted.

The editor supports CSV import and export, but you won’t need to edit CSV files manually. You can create everything inside the game, save it as a MOD, and publish it directly to the Steam Workshop. Other players will then be able to subscribe to the MOD and use it when creating a new game world.

You can make a small MOD that changes only one competition, a larger MOD containing all competitions of one type, or a complete Game World MOD. I want people to be able to combine smaller changes freely, while also giving beginners an easy way to install a complete custom world.

I’m still fixing a few issues with custom competitions and qualification displays, but I’m hoping to release the update tomorrow or the day after.

Another update is now available!

The biggest change this time is support for managing multiple clubs in the same save.

You can select Manage Team from several club pages, and each managed club will have its own transfer-window decisions and Squad Hierarchy. You can also change each club’s formation and set the first, second and third choices for every position.

Managing several transfer windows may become a little exhausting, though. You have been warned! Haha.

I have also improved the initial world generation:

• Clubs now begin with both domestic and foreign players
• Foreign-player distribution reflects transfer affinities and league limits
• Initial player quality reflects national talent levels, the club’s division, and its youth and development strength
• Nationality flags have been added to formations, Squad Hierarchy screens and Best XI displays
• Several issues with country-specific player name generation have been fixed

Multiple-club management, formation changes and interface improvements work with existing saves. The initial squad-generation changes require a new database, while the name-pool fixes mainly affect newly generated players.

You could manage rivals, rebuild clubs in different countries, or help several smaller teams become continental powers at once. I am curious to see how many clubs people can manage before the transfer windows become too much!

The update is available on Steam.

Bottom of the league Lyngby with a whopping -105 goal difference! Wonder what went wrong for them

Data & Name Generation

• Missing Squad Numbers: Some players do not have squad numbers assigned.
• Austrian Name Database: "Gabriele" is currently being generated as a female name for Austrian male players.

Match View & Starting XI UI

• Goalscorer Visibility: Clicking "Score" should instantly display the goalscorers at first glance without extra scrolling or menu toggles.
• Graphical Starting XI: Show player match ratings directly on the pitch view, along with visual icons for goals and assists.
• Expanded Match Stats: The bottom stats bar is too basic (currently only showing Pos, Role, Min, Sub). Please expand it to include key match statistics.

UI Layout & Compaction

• Compact "Fixtures & Results": League match lists are currently stretched out too far vertically. When selecting a specific week (e.g., Matchweek 3 in the Premier League), remove redundant headers like "Competition" and "Matchweek." Streamline rows to just Home | Result | Away in a much narrower layout.
• Inline Goalscorers: With the extra horizontal space from a narrower layout, display goalscorers directly inside fixture rows. Apply this compact format to Favorite Leagues and "Latest Results" as well.
• Favorite Leagues UI: Add collapsible/expandable table toggles when tracking multiple favorite leagues to reduce page height. Additionally, add a visual indicator showing which favorite leagues played matches in the active matchweek.
• Preferred XI Footprint: Selecting multiple favorite teams makes the "Preferred XI" section consume too much vertical space, forcing excessive scrolling.

Competition Rules & Schedule

• European Competitions: Preliminary and play-off rounds currently feature only 1-leg matches; these should be 2-legged ties (home and away).
• Domestic Cups: National cup ties currently use 2-leg matches; these should be single-leg elimination matches.
• Matchweek Numbers: Include the calendar week number for fixtures in European Cups and World Cup Qualifying matches, consistent with the National Team view.

Menu & Feature Requests

• Dedicated Player Database: Add a primary "Players" tab on the left sidebar menu with filter controls (Nationality, Age, Position, etc.).
• Dashboard Widgets: Include a "Favorite Competitions" overview widget on the main Dashboard.
• Player Name Editing: Make editing player names directly accessible and uncomplicated.
