I love Skate2. It's the best when I'm on the phone with work or someone boring & I need something to do while they blather on...
My one gripe is that you can turn off traffic, pedestrians, cops, etc., but there's no way to turn off the other skaters. There's several bowls and pool spots that you can hardly skate because the other skaters continually get in your way - & they actually TRY to get in your way (& then yell things at you). Funny, but kind of annoying after awhile.
Also, doing any lip tricks on transition pretty much sucks - would be cool if they fixed that.
