Had some extended time at the Grand Central demo pod today. A few more observations:
-Lego Star Wars III: More impressed with this than I was originally. The framerate issues aren't as bad as they seemed at first - it runs at 30fps most of the time, even if the drops are a bit more frequent than I would like. I also thought the graphics were pretty good, with what looked like some solid use of shaders. This was the only game I played that made me wish 3DS had a larger, higher-res screen; the characters are just too small considering their distance from the camera. FMV cutscenes, apparently captured from the HD versions' in-game cutscenes, look nice in 3D as well. Gameplay-wise, if you've played one of TT's previous Lego games, you know what to expect.
-Pilotwings Resort - Controls smoothly, with really nice visuals; a bit simple, but extremely colorful and attractive, with impressive lighting during the evening flights. I just wish it ran at 60fps, which, oddly, it seems to provided there's nothing on-screen but the sky. I also think I get why the max 3D setting on this has gotten so many eyestrain complaints - while your Mii and his/her vehicle almost always pop out from the screen, the environment is frequently so far away from the cameras that it's rendered as 2D. That sharp contrast in depth might be problematic.
-SSFIV3D - Wow, how did anyone ever mistake this for a 60fps game? The 30fps 3D mode still looks remarkably close to the console versions (dioramas aside), though I wish the demo had allowed access to the 2D-only 60fps mode.
