I used to be an achievement slut because I had no money and making a number next to my name go up felt good. Don't care about that stuff at all now.
I got all achievements in Elden Ring because it was fun. Before that, the last game I 100%ed was Ninja Gaiden II. And I've finished Mario 64 with all stars and some other platformers and puzzle games and shit.
I really like JRPGs and would probably 100% some of those for fun but basically all of them have some stupid quest where you need to talk to a guy outside a cave but only at night and it has to be raining and it can't be before you've beat the boss to the area and you need chicken soup in your inventory and it has to be Thursday in real life and if you miss the quest then you're locked out of it for the entire game. This shit is just obnoxious.
