there is no doubt there are real benefits to some games if they were in 3d, but there are too many problems with the systems as it is now. they cause many people to get dizzy and have headaches after an hour or two at most of gameplay, i dunno about you but when i play games i often play twice as long as that and i never get dizzy or have headaches.
the glasses are noticebly heavy, nevermind if you already wear glasses. and can get uncomfortable themselves over time.
your fps is going to suffer particularly on consoles since the rendering has to be split, i mean how many games need downscaled on ps3 and xbox 360 just to get 30 fps out of them? now we are going to add 3d? what are games going to need to be rendered at to crank out twice the fps for the 3d effect, and to get playable fps?
there are prototype 3d tvs out there that do not require glasses and maybe they will be better since you wont need the shutters on your eyes that probably contribute to the eyestrain a great deal, but i dunno anyone that has seen then in action or how good they are now, but maybe they are the future of 3d, in 5 to 10 years.
movies are a whole nother story, the fact that many movies just tack on 3d after the fact trying to gouge some money out of people, but the effects can range form awful to ok via that process, avatar was built form the ground up with 3d in mind and and it worked well because of that.
3d is the future of gaming but it a nother generation or two from being ready for prime time. me i am going to be plenty angry is the resolution of my games suffer i am playing in 2d because now they will have to accomidate 3d and the 5% of people that actually are going to invest in new tvs plus the glasses to even use it.
