Ahh, after looking it up, I recall reading the back of the box as I was looking through the PS3 games at wal-mart the other day.
I don't see why the 360 shouldn't get it. I mean if the amount of people with microphones is an issue, don't a lot of games have the option to mute? Or have an option to turn off mic chat all together?
I'm sure it is capable of being made for both systems, regardless of specs, why not? I don't see why people feel that games should be exclusive... I mean I understand why there are exclusive, like GoW and uncharted for example... It's just that, beyond the xbox 360 and ps3... We're all gamers looking to have a good time, and if a game is capable of doing that on both systems... Why not?
If the game can't due to the systems specs, then there's nothing that can really be said or done unless the developer is willing to adjust the game accordingly.
The above statement that a game where xbox players and ps3 players could settle their differences accordingly sounds like something that would be a LOT of fun. I would buy that regardless!
I think a proper name for it would have to be "Fanboy Fisticuffs"
