As a previous review mentioned, you should get the free version. But it is not a freeware version, it's an open source/free version. The difference is important. In 2002 (ten years after 1992), Toys for Bob (the developers) released the source code to whoever was willing to update for modern platforms. They have improved of some aspects of the game, but have decided for the most part to remain entirely true to the original game. With the source code freely available, anyone - including you - can modify the game as you desire. You just cannot distribute it under the name 'Star Control 2'.
