I've read the last few pages of this mess going back and forward and I really feel some of you are just dismissing the system as a gimmick and totally blowing off Granville, though he is only using Rayman to make a case.
Pilotwings I think is a better one, similar to Rayman but in the air so you don't have the shadow. With the 3D flicked on it really does give a far better sense of location on the screen versus the obstacle/ring/point block you need to hit and it helps vastly with precision. I've tried courses with it on and off and have performed tighter better scoring when I can see where I can edge something versus just judging false distance on a flat plane since I don't have the shadow crutch. Shadows are great, they truly do help, but having actual depth helps in a more real way just as we move in a 3D world in real life so we're born to getting distances.
Along that line another that fits it well is Ridge Racer. It's more subtle than Pilotwings where the rings and things pop. The game takes that more real feel I'm talking about and applies it globally across the screen. Shadows don't come into play here as you're on four wheels, but what does come into play is the depth of your car, depth of the course, position of ever closing on you walls, turns, obstacles, other cars, buildings, etc. Sure some is eye fare like the airplane you see in online images, but when driving around other cars I think it gives more of a natural feel to passing a car and judging proper distance as one does in a real car.
I think the 3D when applied wrong is just stupid eye candy and gives wow but no substance, much like how Street Fighter pops up like the old arcade Sega Time Traveler hologram title as the characters pop out largely and round, terrain is fairly flat, just like that old game -- it's eye whoring. But, in games where it gives a more real and better sense of natural depth, that's where it really does add something more than being just a dumb gimmick as some are passing it off as.
