nah g4 is a usa network show, not on cable or satelite.
we get the gamesnetwork, only problem is most of its programmes are broadcasted from italy, so there in italian.
I have noticed bravo has a games show each day around 6pm (either on bravo or bravo+1 on digital). Seems to be pretty decent, some good reviews and its very up to date. Often have interviews with designers\companies.
actually just checked there, its finished for the moment and has been replaced with the the dukes of hazard…
