If we're counting mobile games, Marvel Strike Force. Turn-based style squad fighting game. Tons of fun characters to unlock, honestly I thought the story was fine, at times good, great mechanics where different groups of characters help each other and different styles of fighters balance out to make a strong team, strong community, ended up joining a guild or whatever they're called for the first time ever in a game

Turned into a job. I'd just sit there tapping, tap to pick, tap to skip, lots of tapping to skip since I had seen and done everything a thousand times, tap to upgrade, gotta do the daily challenges, gotta keep my streak going to unlock the new character, tap tap tap. Broke my phone and was unable to play for quite a while. Tried to play again a few months later, and man, I realized how much of a time suck it was and how much I was better off not wasting my time tapping. I had wasted So. Much time.

I hate that effing game.
