Tony Hawk's American Wasteland is a very good game with very good graphics and variety of tricks and grinds. There are lots of different levels and there is no nude or vocal explicity. I bought THAW for $20 UK or $38 US. There are hundreds of tricks like grinds, fakies, ollies, mctwists and manuals. This game is pretty fun for the beginning but eventually loses its variety and you just want to try and kill the guy. I like trying to make him mess up then make his insane bar go full and then he cracks his head on the skateboard :)
But overall, this is a good game and full of twists and turns... LITERALLY!
