X! This venerable series of space sims is a must-play for genre fans, and now it's all kinds of cheap. A shade short of a fiver will net you the entire series, all of its expansions and even the prelude to the next episode. Explore, trade, battle, upgrade... we love space sims so much, and X is up there with the best of them.
