Gekkeiju Online: http://gekkeijuonline.com - further proof that lone wolves CAN dev a mmo. Currently in its like 5th incarnation's beta (actually publicly closed until dec 31st since she (yes the designer is also a girl) shut down the old world until she is releasing the new beta publicly. Luckily I have contributed to the game and am fairly well known in the game so I got the closed beta invite. It's also nice because its very tweakable and in order to play (decent) you need to be a little smarter than your typical mmo player. Graphics aren't great but they are getting better. Made with Irrlicht and Raknet.
