make it so pc gamers can join xbox games iff they have a 360 controller plugged in and are using it to play the game. yeah kinda lame but then at least if you have GOW for PC you could play with xbox people without actually owning an xbox.
I mean seems like a simple enough solution to me anyways. I’m sure there is some way microsoft can code to only allow XBL gameplay on PC if a 360 controller is present.
