Space Colony HD is a remaster of the real-time strategy game and base builder developed by Firefly Studios, creators of the Stronghold series. It’s a strategy game with depth and personality.

Does not open on my old iMac white using 10.6. Intel core Duo Opens on my iMac Silver 10.9 Screens flickers, have to use 800x600 it does not flicker, could be the graphic card 8800 GTX. Works on my i7 GTX 660 perfectly.

Tested on 4 Systems. Might be different on yours, Maybe works after new install of osx, or maybe graphic card got bugged. If it works on your system you can comment.
