also 3D technology would do a world of wonders for the horror game genre and some rpg games, shooters will be abit difficult to comprehend in 3D you'd be limited to the stuff that could be used, shrapnel, bullets, explosions, body parts..thats about it that I can think of it would make shooters more difficult to playthrough not being ale to se a bleeding thing. hence the reason I think 3D technology should stay away from games except the horror genre as having things jump out of the screen at you screaming and trying to maul your face off I would find pretty amusing.
as for the other game genres while its a long long way off I'll wait for something like full virtual reality before I get excited.
