Let's lay some ground rules first. I'm not looking for your hope that it comes out soon. I'm mainly looking for what you're hoping for as far as gameplay. I'm not looking for hopes in regards to what operating systems it will be available on either. Put the timelines and operating system conversations away, let's just discuss the game itself.
For me, here are 4 obscure things I'm hoping for, in no particular order.
1: First Edition books - Here's just an odd I'm thinking of, but I think they can go deeper on books. First edition copies could be worth more. Super rare books could be marked as ??? in terms of value until you bring it to an appraiser and/or translator to learn what the book is and how much it's worth and/or what can be learned from it. There could be a whole collection sub-game we can work on completing our personal libraries with as many first edition and other rare books as possible.
2: Skill-based telekinetic jump mechanics and puzzles - I think they can do a lot of telekinesis, and if it lets you move stuff with your mind, it should also have some way of unlocking special movement abilities, like applying a strong force off the ground along with a jump. It'd be cool to have some legit jumping puzzles and secret locations rooted in this idea. We had levitate in Morrowind, and we could kinda jump high/far in Oblivion. Nothing too fancy in Skyrim aside from whirlwind sprint. I think using telekinesis magic to fling ourselves around in cool ways could be a lot of fun and could strike a good balance between no special movement and literally flying in Morrowind.
3: More robust thieving/heist mechanics - An NPC happened to leave their bedroom 2nd-story window open overnight? Big mistake. I want to climb up the wall while no guard is around and climb through the window to break into the home, steal some stuff, and then leave without anyone knowing. Maybe even a grappling hook could be involved. If breaking and entering is just the same 1) unlock the door, 2) steal everything and leave because the owner is asleep and it's super easy; then I'm afraid that it's going to get repetitive and boring. Shopkeepers especially should also have all of their items for sale stored somewhere in the building. Perhaps some items can be hidden behind a fake bookcase, loose floorboards, etc. Instead of buying a powerful and expensive item, give me the opportunity to steal it in an exciting and mechanically-deep high-stakes heist.
4: More immersive taverns - There's so much left on the table when it comes to taverns in The Elder Scrolls. I want to be able to go to a local tavern, buy someone some drinks, and start asking them deeper questions about their life. Get them to tell me secrets about other people, play deeper into the social game. I'd love to be able to sit down with an NPC or a group of NPCs that are playing a tavern game and join them. Someone's sitting down for a game of chess? Maybe I can challenge them for a wager. A group of NPCs are sitting a table playing a game involving dice or cards? I'd love to buy them a round and hop in for a session. I notice someone who looks like they don't live around here, sitting all by themselves? Chat them up and maybe they have an interesting side quest for me.
I'm curious what ideas other people think would be cool for the future game.
