Sidescrolling fighters are probably the ones best equipped to put in decent graphics and whatever technical overhauls are needed for 3d effects. They only need to make the fighters come out of the screen to make it good too.
However, I was in Curry's the other day and I was looking through the TVs, and the 3d telly they had on display DID NOT WORK AT ALL.
The glasses didn't make it 3d, they just made it darker (you could still see all the lines that are meant to be in 3d, just as if you weren't wearing the glasses). If that's their example of 3d, I don't understand how it will ever take off...
EDIT: is the poster above me wearing a Junior Senior: Move your feet music video avatar?
You sir, are awesome. Quote does not seem to be working though...
