When you hear “Free” and “MMO” together there is usually a catch. Sure this is often the high tag price on the box or the money you have to spend on game currency. Amazingly, there is a site that keeps up with truly free MMO games out there.
The site is called MMOHub and it lists, in detail,various free online massive multiplayer games including reviews, screen shots, game play videos, and more. I found this to be an extremely valuable resource while researching for my daily gaming podcast.
