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.
Super Mario World (I 100% it multiple times)
New Super Mario Bros Wii (I 100% with friends and we still play it time to time via Dolphin Online)
Mario 64 (Also did 100% multiple times)
Mario Galaxy 1 and 2
Super Mario Bros Wonders (I also 100% two times already)
Super Mario Odyssey
Super Mario 3D World + Bowsers Furry
Super Mario Sunshine defiantly NOT!
HOLLY MOLLY to 100% this game you must be a real masochist!
Besides Mario Games: Zelda Majoras Mask, I love this game
Ocarina of Time
Elden Ring (I 100% The Base Game a few times, once Singleplayer a few other times with Seamless Co-op)
