A space based MMO called Darkspace made the transition from pay-to-play to free recently. I betaed the game several years ago and it was rather entertaining. Graphics are decent, gameplay is well thought out, and the community is small but strong.
The game is completely free up to the rank of 1st Rear Admiral, to advance past that you must pay for the game (the rank is decently high up).
