I didn\'t care much for the movie itself, but Avatar had the best 3D as far a cinema goes.
At home I have Thor, Cars 2, and Ice Age 3 and the 3D does add some depth to the movies, but it\'s not like Avatar in the theater where it was floating out of the screen.
As far as games go, the 3DS is decent for some titles, but the screen has to be held at a correct angle to properly keep the 3D effect and a clear screen.
On PS3 one of the best 3D examples is an old school type game, Super Stardust HD. It has a really nice look to it, and the explosions, whether it\'s you or one of the bosses, really catch your attention when they come flying out of the screen. There\'s demo on the PS store for it. Also try the demo for Sonic Generations. That was the first game that had me grinning like an idiot as I saw how cool some of the effects were on my TV after I bought it. Other recommendations, Crysis 1, Dungeon Defenders, de Blob 2 (it\'s highest 3D setting was too strong, I have to keep it at a 7 or 8), Motor Storm 3D Rift (basically a $10 3D demo, no trophies, just 10 tracks and one or two vehicle selection per track, still for $10 not bad), God of War Chains of Olympus (I haven\'t played the second PSP to PS3 port yet, but for the first one the 3D effects really made the game more immersive), Resistance 3 (I only played a little of it to try out PS Move and the gun that came with it, it seemed pretty decent, but I would recommend using a controller over the gun and Move).
Also, Oddworld Stranger\'s Wrath will have a patch next month making that 3D as well.
