I don't play any MMOs at the moment but I've been considering it. The problem is that I'm not that interested in being part of an online guild/group experience. My gaming time is my alone time. However there are a number of open world type games that I have always wished for, but it seems they only exist as MMOs. For example I have played many Lord of the Rings games but always wanted one that just let me explore the world of Middle Earth. Right now I only see two options, Angband (which I do play and love) or LOTRO. I've also always wanted a proper Star Trek RPG that let me explore the universe, but it looks like Star Trek Online is my only option there. There is also the Create Your Own Superhero fun of City of Heros, I have a few superhero games but they are limited to licensed heros. Since these are all F2P I'm thinking I might try them out, but I havn't made up my mind just yet.
