Tales of Pirates is alright if you have a LOT of time to spend...
Diablo 3 looks like a good choice since it's got the auction center for paypal transactions (you get real life money for playing -- legally!)
I would recommend dofus. If you like the play style of ff tatics then you will love this game as it is very similar. It is a strategy/adventure game and has a huge world. You can subscribe with ogrines (although that will take you a bit of time to get enough money to subscribe every week).
