Chance to buy it? THEN BUY IT!
Whatever, my dad bought me a new after som months and that's when it happend... I fell in love with TH:PS2! I played it so much that I really thought I could be a skater myself, (what a nice dream). After beating the game a couple of times with almost all the characters, including the unlocks, I just stopped playing it. I don't really know why, but maybe cause I played it so much, each and every day, non-stop, for 7 months. And I even tried to beat my brothers friend, which had reached around 500k points by only grinding and doing manuals. Sadly, I never accumulated that much points.
Even though the game is kind of old, I still play it, and I find it much better than all these new skateboard games where everything is realistic and you can't do sh*t but a single trick. Well, that doesn't happen in TH:PS2. You can do everything! It may sound sh*tty by now, but seriously, it isn't! The game still gets me everything I see the CD. I feel like "oh, I want to play it again..." and I do it.
After mastering lots of tricks, you do become a pro skater, since you can jump around, grinding, kickflippin', manualin' or just do the 900 with Tony Hawk.
I'm no good writer, specially not in English but I hope this gives you a good view of the greatness of this game. ;)
