Game: Pirate Galaxy

Pirate Galaxy is a browser-based free-to-play MMO that's making itself available on Facebook like so many others. There are a few unusual things about this particular game, though. For one, it's written completely in Java instead of the usual Flash, so you may find yourself having to do some Java installs before you can play it. The game's theme is pure science fiction, with the player controlling a spaceship instead of any sort of human avatar. The 3D graphics create some extremely impressive landscapes compared to most things you'd see on Facebook, but the gameplay itself is fairly standard.
