MMORPG or just RPG?
If you want a good MMORPG check out Lord of the Rings Online (going F2P soon) www.lotro.com
As for regular RPG...hmm...elder scrolls, FF13?
sorry that's all that comes to mind at the moment. >.<
LOTRO is going to be F2P as in you don't have to pay at all for the game to play or like theres gonna be no monthly fees??
