Yeah, $5 doesn't hurt, but I quit THPS at 3. I'm sick of doing different tricks only because they are different and serve no other purpose. Tricks are tricks in real life because they are SO HARD TO DO. You don't have a feeling of accomplishment when doing tricks in these sorts of games.
It's only $5 and has some high scores, but if it's just another THPS, I think I'll pass and not waste my money.
