i saw it maybe 3 years back. it looks and works surprisingly well i remember. and that was a while ago so they must've upped it quite a bit for todays standards. though this would never appeal to serious gamers, i can see it appealing to large groups of casual gamers though.
hmmmm i wonder how the response is for like a shooter, seems like it would be great for the wow stuff or role playing ones, but how fast would it be for shooters if you got all your info from the cloud?
i guess servers kinda already do some of this but i would consider it half right now, all of it... wierd.
