I'm a little aggrivated. I've got both PS2 and Wii versions, and here are my gripes:
The PS2 and PS3 have the option to output optical audio which sounds crisper than regular RCA. The Wii only has the left/right RCA cables so the sound seems a little duller. Maybe it's just me, I dunno.
Second, remember when Ready at Dawn said it was *almost* 16:9 then retracted their statement? Well they were right the first time, there's still little thin black bars down the sides of the screen. Not that big of a deal, but still.
And finally, my biggest gripe of all... the god damn celestial brush... REQUIRES you to be perfectly horizontal with the remote. For example, if you hold your remote at a more natural 45 degree angle (in terms of it's rotation, not like you're pointing up at the screen, but rotating your wrist naturally) and then move side to side with your arm, the brush moves DIAGONALLY. What the

! I can do this on the

ing Wii home screen and move side to side. Instead it's like a computer mouse?
*sigh*
I'm not sure what to do. I guess I'll put a bit more time into it but so far I feel like I just got ripped off. And it's not like they can patch the game, either. Thanks, Ready at Dawn.
EDIT: While the forced horizontal orientation of the remote is still a bad call (unless there's some strange reason for it), I just played a bit more and I feel much better. I got used to the mouse-like movement of the brush. I think my only remaining gripe is the reduction of the paper canvas visual effect, but hey, whatever.
