Has this ever been discussed yet?

Ok I haven't been on this in a while so I have no idea if this was discussed or anything so don't act like I'm some idiot. But do you guys will ever think they will create a way for people to play online with each other on the same game but different systems? For example playing Modern Warfare 2 on my Xbox 360 and I would play other players who are playing on their PS3's or PC's.

Hasn't it already been done? I thought there were a bunch of games that would allow PC users to play against xbox users, and vice cersa.

I doubt that it will ever happen with the PS3, and there are only like three games that support cross-platform multiplayer between the 360 and PC.

The pc takes some advantages, but apart of that is possible.

They did it with Shadowrun, it worked pretty well with the exception of the lack of PC players. It was a lot of fun playing with my friend who didnt have a 360.
