Wasn't expecting a lot from this title (from Triongames)
http://www.trionworlds.com/trove/Currently in open beta, its F2P and very accessible as a F2P game (there is very little in the store that isn't available for in game currency that you can earn for doing the single daily)
Its pretty much Cubeworld (if anyone knows that game) but it has a dev team that actually does stuff that isn't at a snails pace.
I'm finding it far more fun than the AAA MMOs that have been released this year, especially the newly released Candy Barbarian class
