I'm with the others that say this 4X turn-based strategy game beats all the Civilization variants hands-down - in spite of its rather aged and simple graphics and small-screen appearance - because of the slightly wacky, factional-centric story line and science-fictiony alien planet discovery elements as well as the easy game-play (after a learning curve). If you haven't played it before, you will have some surprises and lots of challenges! Plus, unlike the Civilization games, you can stack unlimited different units on the same tile at a strong-point, meaning you do not run out of places to put your units and can capitalize on terrain advantages.
