It's your last chance to get the Offworld Trading Company prototype through the Founder's Edition as that will be ending this Friday.
Post from Soren:
Offworld is progressing nicely, which means that we are ready to move forward to the next phase of the game’s development. Thus, the Founder’s program is going to be closing soon, specifically on January 16th. After that, the game itself will not be available to new purchasers until it goes up on Steam. Right now is your last chance to buy and play the prototype and join the private forums.
