Plus, Fire Pro Wrestling is cheap ($15-$20), has a great create-a-wrestler mode (or create-a-fighter, I guess), and is the best wrestling game on the PS2 to boot. Every person with a PS2 and even a passing interest in wrestling or MMA should own this game. No excuses.
I used to have UFC Sudden Impact on the PS2. It was cheap, dated, pretty easy, and played just like the UFC game for the Dreamcast if that means anything to you. I made a pro-wrestler in the create-a-fighter mode, and made people tap to the figure-four. Fun enough for cheap, but I eventually traded it off.
For gameplay, if you want a more sim-approach to the sport, go for NHL2K3. Typical games won't be high scoring and you need to set up some team strategies if you want to score. If you want a more arcade approach, try NHL Blitz 2003.
