yea, the halfpipe comps are completely unrealistic...   i mean fuck...   they make you go up and down the pipe over and over doing stupid trick combos...  and i can't even get 1st...
plus, one of the shread challanges was to handplant 11 of the marked rails...   i gotta ask you - who goes around handplanting a bunch of rails...   it's getting silly - i think they just ran out of idea's halfway threw the game and were just like - fuck it, lets just make our own shit up now.
