A while ago I took a trip to San Francisco and stopped by Alcatraz. It sparked an interest in playing THPS4 again and, after weeks of searching, I finally found it at Entertainmart for $4. I must say, this game kicks ass. It's exactly as I remembered it, and it's a shit ton of fun. So I just wanted to say that if you manage to find it anywhere, you should definitely pick it up, it's totally worth it to replay the game, or even to play it for the first time.

While it's not a bad game, I do think it's the worst of the Pro Skater games. I still had some good times with it, though.

1 and 2 are King.

I have no problems with Tony Hawk 4 to be honest, I thought it was an amazing game.
 
American Wateland however....

THPS3. That is all I have to say on that.

I really did enjoy Tony Hawk's Underground, though Underground 2 didn't live up to it's potential, I thought, and things just had gotten way out of hand by that point.

Tony Hawk 4 was really fun.  The last decent TH game was Underground. THUG2 was okay. 
 
I still like the first two the best.  3 was fantastic as well. 
 
Aw crap, now I have to find and play them again.  I have 1,2,3 and 4 still (And American Wasteland but that sucked) so I should be able to find them. 
 
My cousin and I STILL play THPS4 whenever I'm at his house.  We have for every year since it came out, and both used to be insanely good at it.
