Best PS2 games? - eviltoast

I bought a PS2 about 6 months ago from a coworker and finally got around to getting it working at a good enough resolution on my monitor. I currently have:

  • GTA 3
  • GTA Vice City
  • Gran Turismo 3
  • Matrix: Path of Neo
  • Katamari Damacy
  • Midnight Club: Street Racing

Any other suggestions? I know off the top of my head I want to get the SSX games, maybe some sports games, and of course the MGS titles that came out on PS2. Anything else?
