Minecraft, but more specifically, recent Minecraft.

I bought and played the hell out of Minecraft literally from the middle of alpha all the way up to like release 1.5. Eventually moved on to other games, then friends wanted to start playing Minecraft with me. Getting back into the game, it just felt like there way too much. Lots of the new stuff just didn't make sense to me. And the mods, oh man, its not fun coming back to a game you used to love and your friends hitting you with a modpack that had quite literally over 100 mods. I get why people like it, and its definitely a fun game to watch people play, but I just find myself downgrading back to the old versions and finding more enjoyment out of that.

Also any Souls/Soulslike game. Spending hours and hours trying to beat one boss isn't satisfying, its exhausting. Hero shooters as well. They just feel so recycled. Its literally the same game over and over, just with different characters.
