What game is the weirdest or just dumb? Yes , weirder than goat simulator. Just now I discover the existance of a game where you are stuck in a room with a red button in a pedestal with lots of signs and posters that say to push the red button. The name of the game is "Don't Push the Red Button" .
Duck or something...not bad but playing as a duck stealing stuffs was weird.... I'm sure there were weirder ones...like adulterated ones with sperm race leagues and all...but they are just straight up bad and played it for lols... Heck a guy even fooled the librarian that it was a game of white tadpoles XD, that was funny as heck.
The visual novel Euphoria. I can't go into details, because it has an 18+ rating and I seriously don't recommend playing this game, although it is very high quality and has a very interesting story, especially if you like horror/mystery movies like cube, saw etc., but it is also maybe the most disgusting game/movie I've ever played/watched in my life and believe me, the skip button will be your best friend

I am not a fan either but they're not that bad either since it's just still images. Honestly, I was more disturbed by the cultish plot since cults really creep me out.
