Mr Driller Online is a "laggy mess"
According to X3F, the Xbox Live release of Mr Driller Online is something of a disaster when it comes to multiplay, which is a little unfortunate given the game's title. There's a video through there showing fairly ably that it doesn't work so well. 800 MS Points well-spent, there. Maybe we won't bother after all.
Update: Oh dear. IGN's given it 2.8.
