If your broke like me at the moment go with PC.
why? Cause for PS2 u need Network Adapter, Game, USB Keyboards, and Hard-drive.
For PC all you need is the game.
So I will decide when the game releases to get PC or Ps2. it all depends on how much money I have. I rather play on Ps2 cause my living room is more comfortable then my computer chair, but like i said I'm broke atm.
