My son has TH3 for GCube and we both love it.
We rented TH4 for a week and liked it as well.....but I had no urge to drop another $50 on basically the same game. I would save some dough and get TH3. (we got it on sale with a mem chip for $20 @ BB a few months ago)
NOt taking anything away from TH4 it is a great game.
Aggressive Inline was fun as well (same thing sans skateboard) once the $$$ drops on it, I may get it for his birthday.
We just bought ROCKY and it is f-u-n.......the storyline could have been better, but it follows the movies and the boxing is where its at anyway

When Rocky left-hooks, you can swear you were in the movie
