So, The other day after messing around with the Spore Creature Creator, and creating a few versions of Fwiffo(who hails from Star Control II and is the alien whom i've borrowed my moniker(sp) from) I decided to download "The Ur-quan Masters". Which is the free source code somewhat updated Star Control II. You can download it at sourceforge. It has been rated as one of the top games of all time by EGM and Top Hundred games by IGN.
If you go to spore.com and check out the sporepedia and type in Star Control II you'll find countless creations based on Aliens from the game.
If you download the game and enjoy it, stop by toysforbob.com and send an e-mail thier way letting them know you would love to see a true sequel made.
