One of the best games ever if (a) you're a Star Trek or scifi fan and (b) can round up three players.  There's a lot of strategy to this, along with resource management.  It's a 4X game.  There's some luck to it too, however.  If, as one player, you consistently draw multiple Warp 3 planets or hazardous phenomenon before you've improved your shields--and particularly if someone else draws nothing but uninhabited worlds ripe for the picking--good luck recovering from that.  It can be done, but you'll need some Trade Alliances and excellent gameplay on your part.
