I'm rater out of my depth here, but my son is looking to find an RPG game fro his xbox 360. He's looking for something similar to Runescape/nostales/wow in other words a n on-line games that goes on and on and on.... He recent purchase Assassins Creed lasted three days before he completed the main game so a bit cheese off at the cost for such a sort game. Any recommendations please for use on his Xbox 360? We are in the Uk and he has a Gold live account.
