Is there a technical reason why there isn't any cross-platform gaming options available? For example why PC can't play against Xbox or PS3 players in common games like CoD: Black Ops, Unreal Tournament or Dirt2? All you're doing is hosting a server with the game code - whether you're accessing that server via console or PC would seem to be irrelevant. Was chatting with a co-worker about it. I'm aware that tests have been done and PC gamers with a keyboard and mouse absolutely smoke console players trying to use a controller in first person shooters. But I can't believe that's the only reason developers/producers don't have multi-platform playing options. The possibilities to make money via ads and sponsoring servers in a multi-platform enviornment would be hard to ignore. Anyone have an idea about this?
