See, there's my question. As someone who can see color, I think color images are much better than black and white for video games (though you can still play them in B/W). I'm happy color TV was invented and wouldn't want to go back to B/W.
On the other hand, the difference between standard-definition images and wide-screen high-definition is almost negligible to me, and I wouldn't have minded very much if HD had never come about.
What is the difference like with 3-D? Once you see a game in 3-D, is there "no going back", or is it just a nice additional thing to have?
