check out this race vid. there's a bunch of acrobatic stuff going on. it has the secret unlockable character on it tho.I haven't actually played it yet, but I've seen friends play it a lot. It doesn't seem to compare to Mario64 or even Sunshine, to me. There seem to be a lot of limitations. I remember in 64 and Sunshine being able to cut the course times down a lot by doing long jumps and wall jumps, etc. etc.
Galaxy didn't seem to really have that with the jumping from planetoid to planetoid thing.
I'm not sure; I haven't played it yet, but that's my initial impression.
