I guess it depends on personal preference whether or not you want to play games in 3D. For me, 2D games has become quite monotonous. I mean the adventure is still exciting and all but I want something more, something better. And 3D gaming is exactly the remedy for my dissatisfaction. When the 3D is in HD and real good it makes you become a part of the game, and you really feel like you're in the world itself. It's a new layer of excitement. Granted, you can get lost in that for hours on end and have no work done, but it's amazing when you're really into it. That's the way I see with my 3D gaming experience. And I'm willing to bet there are many others who enjoy it too. So give it a try, maybe? You might even enjoy it more than you think.
