The talk about game tv shows brings to mind g4. When I was in the states recently, G4, which is like a channel for gamers/games, had some slick content.
It had regular shows like ‘attack of the show’ – not just about games, but well done.
They also had other more games related TV.
The presenters of most of the shows seemed to know lots about videogames (as opposed to just presenting).
I amn’t sure whether you can get g4 here (probably available via cable somehow?), but it’s content seemed to have higher production values than shows I remember seeing on tv here.
