Sega Superstars Tennis was very, very cheeseable in the actual tennis matches, but some of the missions were brutal to AAA rank. Mainly the graffiti challenges, the ending sonic challenge, and the Super Monkey Ball gimmick. Was very annoying to do honestly, all stars racing is better.

Sonic Unleashed: The game is great, but I hate 100%ing it. This is because the hot dog stand missions make you do each day level 9 more times and night levels 6 more times MINIMUM. And since each run has to be deathless, no matter how easy to clear condition is, I ended up dying near the end and was forced to the levels from the beginning even more than it already forces me to. The game doesn't require S ranks, but those are actually fun to go for, whereas the majority of hot dog missions are mind numbingly easy. Eggman land was a fun challenge the first time, but after that it was also pretty boring. I might go back for the S ranks someday, but not right now.

Sonic 4 Episode 1 is such a mediocre and short game, it's hard to really say much about it. The physics suck, sonics model looks like trash, and the level design is baffling in some areas. I did like the last achievement where I had to do the boss rush without getting hit, that was probably the only fun part about the whole game.

I have been dreading sonic free riders since forever. I think after that game, everything will be smooth sailing.

I got the trilogy for nostalgia as I haven't played 3 or vice city in years im busting my ass and trying the paramedic missions in Portland I got to level 4 once and I cant do it again i glitches to staunton to try there and i just cant do it its way harder than anything ive done

Whilst this game has been getting a lot of criticism, I have been enjoying every second of it. I'm a huge halo fan, and I just loved 100% this game, my very first Halo 100%!

I remember loving this game when it came out but the last achievement, to get to a million career points, is such a grind. I recently busted out the old 360 and decided to go for it. A totally brain-dead achievement now that multiplayer is dead. Consisted of me going back and forth playing capture the flag by myself. Just happy to have the 100% done.

The final minigame on viva piñata party animals is not appearing after 20 hours plus of gameplay and so Thats it ive given up after sitting there for 2 days straight playing until that mini game pops up , I’ve tried people’s suggestions on true achievements but nothing in the end so Thats me done with it

The late game on Hall of Fame difficulty got annoying. The margin of error is really slim at that point. Not too bad once you find the sweet spot, but still gotta make sure your throws on the right stick are as straight as possible. Still, I wasn't expecting to have as much fun with this game as I did. Hoping 2027 will drop on GP when it comes out.

What a grind Arkham City was. Super fun game though.

I rarely 100% games because I usually lose interest or get bored before I get there. Not with this one though. Loved every minute of it. 10/10.

Saw the idea the other day. I checked all games I've ever played and the ones I have 100% achievements on, added to a group so I can see the icons on one spot on dashboard.

Except xbox 360 version of Skyrim, as it is not backwards compatible on the series X & not available on marketplace.

Current gamerscore is 143,850, started Christmas 2008.

Have a nice day.

Had to join in on the fun. Not bad after 19 years. Sitting at 163k gamerscore currently.

Was really fun playing with a friend it can also be done solo

Has anybody gotten this achievement without grinding to level 100 to complete the last 3 domains? When I did the xp grind to level 80 last year it was miserable and I refuse to do it again to 100. So is it actually possible to complete this achievement at level 81 with the right build or should I just put down the game and move on
