Any Call of Duty game. Although, in truth, the only ones I want to play are MW1, MW2, WaW, and maybe some of the older ones.
The Prototype games.
The Amazing Spider-man.
Spiderman 2.
That new Deadpool game that looks pretty fun.
Anyone noticing a pattern?
Well, I don't have anything against the aforementioned games, but I have a huge problem with Activision, so I boycott them. I may be missing out on some good games, but oh well.
Among others...The Assassin Creed games. I used to really want to play those games...But then Ubisoft did two things I don't like: 1, they said they never plan on fully wrapping up the overarching plot, and they just plan on keep making them until they stop making money. I HATE that. That's why I don't watch TV shows, or read comic books, everything interesting is always just hinted at, and nothing ever happens...The second reason is the yearly release schedule...Dislike that as well. And the Ubisoft DRM is just icing on the cake.
The Fallout games. Only played the first one, probably won't play the others...
Knights of the Old Republic 3 - Because it will never get made. (Yes, I'm still annoyed with that)
