As per title. Most computer games these days are made with such unnecessary padding that I want to murder the devs or myself by the end. See, for example, Hyrule Warriors, the 100% 1000 Hour Nightmare, the Review.
The second game I ever 100%ed was Arceus and I still can’t stand the thought of picking it up again, years later. The first game was Horizon Zero Dawn, which is still fun.
Two games I have platinumed on PS4 that I still go back and play are Subnautica and Kerbal Space Program. Not sure if you mean 100% as in like scan and collect every item, or get all the trophies, cause I don’t think I’ve ever 100% a game in that way.
