The Mass Effect series, specifically Mass Effect 2. The atmosphere, the scale, the characters. It’s the kind of thing where a AAA budget really bring to life things that AA or indie would have had to cut down.

Fallout 4. I have a lot of problems with the story, worldbuilding, and endless minor nitpicky complaints about this game. However it is an amazing accomplishment and when it does something right, it does it very right. The game is the foundation of mods that make it amazing, and while the game didn’t create the mods, they wouldn’t exist without the game. To me Fallout 4 is “I played this game for 800 hours and there’s nothing to do!” kind of complaining.
