It's not bad, but it could be waaaaays better... I know I have to judge this on it's own merit but the existance of the real Trials and many other games in that style make me uncomfortable about this one.
Life bar? dumbs down the difficulty. Stunts, I admit that was awesome, though the inputs were kinda weird from A to G... but still, pretty fun. And the mechanics for rotating the bike to the front or back was kinda bad... so that's it.
