Mario and Luigi 2 looks really sweet, especially the battles, everything is so fluid an animated. I was worried the game would look no different from the GBA version, and I definitely thought that was the case watching things go on outside battle, but the forest area looked a little more detailed than I remember the GBA being, and of course battles were silky smooth with nice animations for all the characters. I really think the Piranha Plants looked the best, in motion though, but I love it. It's too bad the guy playing didn't figure out how to do timed hits until the end of the second video. The trampoline item is crazy. :lol
Mario Kart DS looks nice coming of the DS system, but the other video with it all blown up looked very meh. Still though, looks like a good time, although it definitely shows that there's still work left to be done on it.
I was completely lost watching Trauma Center though. Anywho, thanks for the links.
