Games are only really racist if you consider them racist and let them get to you.
It's like the people complaining about the more recent Resident Evil games. If the heroes are white guys fighting more white guys then people call foul because it's just a bunch of white guys, but second you make a village of Spanish people into zombies you're a racist.
People are seriously reaching for something to complain about when racism is the best they can come up with, hell the whole thing is subjective. If you have a game about a black guy killing a village of zombified Brits then it's still racist. Just because the main character is white doesn't mean the game is racist, just not very creative. I enjoy sandbox games where you create a character because then the claims of racism become really silly and contrived and I end up getting a good laugh.
Satire and racism are two different things, and people need to learn that. Tom Clancy isn't a racist, he just writes things that sell. So you're killing Mexican terrorists in Vegas, doesn't make it racist. I mean, all the white people in Vegas are rich anyway so why the hell would they take each other hostage?
I guess what i'm trying to say is, racism is subjective and calling foul with "that's racist!" as your only argument looks stupid. That and they're just games, if you're honestly spending your time complaining about how racist a video game is then you must lead one sad and pointless life.
