Damn, I typed this huge post, and then saw you've already played Blur.

What the hell, here it is anyway:
I have to disagree with MC here (although I haven't played Shaun White). If you get your expectations in check prior to Blur, it's bearable and you can squeeze a bit of the SSX feeling out of it. Expecations in check means:
- the characters a redesigned and there are no voices. So it's basically On Tour.
- the controls suck. For me, the Ubers aren't the worst thing, the fact you have to press a button on the nunchuk and tilt it for tricks is the worst thing along with flicking the Wiimote for flips and spins. I just hate sudden waggle movements much more than the slower "drawing" movements of Ubers. But for Ubers you need to realise that it will take some work to get the "knack" of them, and you will most likely only use 2 or 3 ubers regularly because you can't get the rest of the shapes to register consistently (I use the heart shape and loop and that's basically it).
- there are some On Tour courses. I hate them since they're filled with trees.
- I
think they also added more trees to the SSX3 courses. Morons.
Pluses:
- some SSX3 tracks.
- DJ Atomika
- the music is dynamic (changes with your trick meter) and helps cover up for the lack of voices. I also really love the JunkieXL soundtrack, but that is a matter of preference.
- it looks nice, on par with the earlier games (in terms of courses, not characters)
- you press A to right your boarder after tricking. This was necessitated because you can't stop spins due to the waggle controls, but a side-benefit is I think you can actually interrupt an uber if need be. Pressing A does take some getting used to.
If you are buying Blur for a serious SSX experience (in particular trying to get high showoff scores) it'll be frustrating I think. If you're buying it just to zone out on some great SSX courses, it can get the job done IF you realise the shortcomings and avoid those. As a massive SSX fan I put it WAY above On Tour (which had absolutely zero redeeming qualities) because of the SSX3 tracks and dynamic music.
I even found On Tour controls perhaps worse because of the damn trick stick. You'd be happily doing a board press with the right analog, then run over a tiny hill and pull off a fucking Uber because you've got the right analog stick pressed in a direction. Then you'd crash.
