Did anyone at all get Madden? I passed on it, initially, since it sounds like it's stripped down to the very minimum barebones, but I admit that I am kind of curious to see how it looks, and I usually only play one-offs in Madden anyway.
I picked mine up yesterday with, lessee...
Pilotwings, Streetfighter, Samurai Warriors, Ridge Racer, Pro Evolution Soccer, Puzzle Bobble, Steel Diver, Rayman 3D, and Ghost Recon. I haven't played everything yet, but of the ones I've had a chance to play, I'd say that Ridge Racer uses 3D the best (and also will make you the sickest if you don't find the optimal viewing angle), Pilotwings is probably the easiest to just sit back and enjoy, and Rayman and Samurai Warriors both benefit nicely from the move to 3D, but without any fundamental change to the gameplay. Puzzle Bobble, in particular, doesn't really get any benefit at all from being on the system, but it's still fun and it's $10 cheaper than the other launch titles.
Fun little system so far, definitely enjoying it.
