I really hate when people berate me for having an opinion that is different than theirs, especially when they berate me for disliking something that makes me extremely uncomfortable (such as fluffy pony comics) . Like, this is sort of like getting mad at a lactose intolerant for being unable to drink milk. I also hate it when people just yell at me for having a different opinion and don't let me explain why I think about stuff the way I do (for example, I like the fanfic Cupcakes because I think it has a lot of story potential.)
Edit: I thought this was about things that make you angry in general. So the game that infuriating to me the most is Pumpkin Panic
