I'm not in a hate spewing mood today so I'll just list off the games I hate and just say they aren't my thing:
Pokemon: Boring, derivative, and not in the least bit fun. They barely change in any significant way, and without any decent story to hold my interest the game falls apart.
Mortal Kombat: Badly animated, poorly balanced, boring, and just overall one of the worst fighting games I've every played. It was only popular for all the wrong reasons and thus it has survived on simple childish gore and nostalgia. The new one I will give the benefit of the doubt as it does seem to be shaping up to be a decent fighter, but this series does not have a good track record with me.
Call of Duty: Everything wrong with FPS games (or at least for me).
