Hey all, I was wondering what the market is like for virtual reality gaming? Have there been any successful companies? Any breakthrough games, in arcade or home markets? When will they become a hit in the next generation machines? Any info would be helpful, thanks.

VR is still just an academic novelty. There are no successful VR games or headsets in the home entertainment market.

VR has not penetrated the home market mainly because of cost reasons. It is used by the military and corporations for training..a lot of the military apps could played like a game and are.
As far as when...that is speculation. The dominent problem is sensor equipment cost like data gloves and magnetic trackers. This has nothing to do with computer power or 3d graphics.
