Yeah, the loading between zones isn't too bad, just a bit inconsistent. Keep in mind that I'm playing this on a hard drive that even speeds up load times.
The use of motion controls here is just to replace digital motion. The one confusing part was that they didn't have aiming with ranged characters on IR; seems like it would have made sense. It's no big deal since I will play with my gamecube or classic controller when it actually comes out, I was just too lazy to grab them for now.
