split-screen play when versing others? After playing Call of Duty 4 and 5, i was in awe of how good the online multiplayer gameplay was. However, in my opinion there was one thing they really left out and that's having the option to play on the one console in online multiplayer with more than one player using split-screen mode. I don't see why it is so hard to put that option in seeing as they have it in Halo 3 on xbox 360. So does anybody know a good Ps3 game like Cod 4 and 5 with this feature ?
