This probably will end up being this game's big downfall. Sure, Sony will sell the 3D gimmick and people will probably buy it in droves, but the technology just isn't there. The red-and-blue glasses have been around for at least half a century, and the technology has evolved far beyond them. If you've ever seen an Imax film in 3D, you know what I'm talking about. Those glasses might work fairly well if you're watching something on a huge screen at your local cinema, but the resolution and size on standard and even HD sets just isn't enough to make it look decent. More than half the people I know that have no problem with watching a 3D film in Imax, or at a regular cinema, have complained about getting headaches after a few minutes of something watched at home with those cheap glasses.
It'll definitely sell, and for those of you who have properly-calibrated, big-screen HDTVs, it'll look pretty good, but anybody playing on a medium or smaller-sized set probably won't be at all impressed, if they can stand it for more than a few minutes.
