These are by far two of the best games ever made. spent so many hours glued to my computer screen, playing the MOO series. You start out in both games as a small empire with the potential to colonize the entire galaxy. research technologies to advance your species and crush your enemies, terraform distant worlds, and in the Second master of Orion, the eventual ability to even destroy planets. at the start of any game, you can choose your race, galaxy size, and difficulty. and because every map is randomly generated, it offers hours of re-playability.
