Say what you want, but at least with a PS2, you're also able to play PS1 RPGs, which as Final Fantasy Tactics, Xenogears, Legend of Mana, Suikoden II, or Chrono Cross. You pretty much have the entire PSX RPG library available to you, which you can play next to flawlessly with graphical and loading enhancements, which beats an emulator any day.
It'll also allow you to play PS2 RPG titles such as Disgaea, Xenosaga Ep. 1 (with ep.2 on the way), Suikoden III and IV (on the way), Star Ocean: Till the End of Time (out by the end of the month), and Phantom Brave (end of the month), to name a few.
If you're an RPG fan to start with, why DID you get a Gamecube?
