Good.
Couldn't do with playing against the 'elitest' PC Gamers on a FPS. The kids on live are bad enough, let alone the gloating you would get from them.
However driving games/fighting games would be an interesting one to do.
Dreamcast and PC owners could play Quake 3 against each other - predictably for the large part the controller players couldn't keep up. You try performing a 360 backflip while headshotting that dude across the map with a railgun. It just ain't gonna happen.
How did that work? I remember doing it and owning the Dreamcast players, but I can't remember what/if anything needed 'modding' to be able to get access to the DC servers.
