Have a look up of Bit-techs take on 3dvision they did very recently, their opinion was in one game, I think fallout, it turned everything horribly pixelated, the crosshair was awful and in general it made the game worse. One of its best games was Batman AA, and when they turned it off they felt it just didn't make any worthwhile difference.
You get expensive heavy shutter glasses that still cost £100, we don't know how long they'll last, the TN 120hz screens are very poorly rated compared to other screens and you only get 60hz anyway in 3d and in a HUGE number of people prolongued use(some 30mins some an hour) gives people headaches.
Its not even close to worth it, the few people that love it are also people that just dropped £400 getting it.
Its a valient effort, but realistically we need a hugely better system that doesn't involve wearing shutter glasses, something that induces headaches in so many people will NEVER become mainstream. Notice how 3d cinema is not done with shutter glasses, because inducing headaches is not a viable commercial idea, at all to anyone with any sense.
If we get far better polarised glasses setups in the future remains to be seen, right now its worth going round to your silly mate who spent all his pocket money on a 3d setup, playing a half decent game with it for a half hour, and then going home, nothing more.
