I've gone back to this about 5 times now after playing other games in between, with an open mind each time, and I just don't really think the game is fun to play.
When you're hurtling down the mountains at awesome speeds, I always feel like I'm just about to lose again, either through some chicane throwing me down a chasm, or some other thing happens where my dude falls off the board and the race is ostensibly over thanks to the utterly useless rewind feature.
I've put a good 8 or so hours into this now, and I never feel like I'm getting better, only more lucky. After a good bit of time on Tricky or 3 I was the BOSS, taking my friends on and understanding the physics of the world, but on this one I think the sudden death elements are out of my control, and completely ruin the entire experience.
What do you the rest of you guys think this far after launch? Have you found yourself going back to it, or does it just not have the same 'one more go' feeling that the first 3 had?
