Any good free mmorpgs out there?

[Mike]

Does anyone know of any good free to play mmorpgs that don't require a monthly sub? I play Villagers and Heroes from time to time but I'd like to add some more games. I know some games don't require a sub but they limit what you can do without one, like The Elder Scrolls Online or World of Warcraft. I don't mind them having in game purchases as long as they don't significantly affect game play.
