I have played many survival builder type games. This one is my favorite mainly due to the complete freedom it allows. The terra forming is amazing and so are the detailed building options! The Dev team is small hence the "unfinished" feel to certain aspects of the game. But they are busy and responsive! The help I got setting up a dedicated server on ubuntu was fantastic! I have half a mind to buy a few more copies just to support the devs! Eagerly awaiting the games current port project over to a newer more flexible engine!
