I'm not a fan of having to pay to play a game I've already bought, but I've been wanting to get into an MMOG so that I have something to do when I have nothing else. Because I have a mac, I'm very restricted with my options. After looking through the available games, I decided that City of Heroes would be something that won't get old with me (for a while, at least). I just want to know if this is a good option. If not, please tell me something that would be better.
