I don't see why the 360 couldn't handle it. The graphics aren't really insane. The control scheme could be similar to the Dark Alliance games, and it would be "un-hackable" if played over Live.
This game is great on the PC, although it has a few bugs that need to be worked out. But, you'd think with that "lack" of games on the 360, companies would bring up some more genres on it. I love FPS's, but geez man. How freaking many more can be made for the 360, without adding in some more gametypes?
BFME2 was a step in the right direction. Although after buying it and playing the first few single player rounds, I'm honestly not that impressed. Personally, I think the graphics and framerate blows. Control seems to work well though, and that's the whole point of it.
This system is capable of so much. I just wish developers would get their heads out of their asses and start making some better games. Yes, I look forward to Gears of War, Too Human, and Halo 3, but damn, do we really need more FPS's, Devil may Cry copies on this system?
Bottom line, if I don't see some real changes in development soon, I'm probably going to sell the 360, and use the money to build a new PC. At least, there's variety there.
