Modern Warfare (CoD4). OK I wanted sequels but not like this, I didn't mean this 'cries'
Bioshock kinda, Bioshock 2 shouldn't have happened, they should've either held their horses and waited for Infinite or maybe gone back, a prequel would have worked better because there's hints at so much in the original while at it's conclusion the two major game players are out of the scene. Bioshock 2 felt like a tack on, even if as a game it wasn't that bad (and in many ways improved on aspects of the original).
Pokemon games, seriously guys I loved my Red and I happily tolerated Gold but what's with this crazy Digimon invasion of the Pokemon universe thing? Uncool man. I like some of the improvements but I think throwing new Pokemon in for the sake of it is a no no and causes a lot of headaches. I mean, how many legendary pokemon are there now? Yeah. (Not that I play it much now but I did and I miss the way it felt)
