I've played Pro Skater 1-4 and have Underground 1.
Underground would have better if the Create-a-Trick mode wasn't so limited. But at least Story Mode was a great change of pace from the Career Mode of the Pro Skater games.
EDIT - Um... I guess I'm overdue to replay this. I forget whether if you're only limited to McTwisting over the helicopter or if you can come back later to do any special trick available at the time.
