Sid Meier's Alien Crossfire

THE GOOD:
-more factions

THE BAD:
-rare to find PC version

SUMMARY:
With the addition of 7 more factions(doubling the original amount), even more strategies can emerge. You can also personally pick the factions you play against(can only choose 7, you included), pitting you against rivals or evening it out so that their are 3 good, 3 bad, and 1 neutral. You can choose to go against random factions too. Unfortunately, they stopped selling the PC version of Alien Crossfire for some reason(why!!!!!!!), so you have to go on ebay or a similar site to find one(if you are lucky). It is worth finding, though.

This ties in perfectly with Alpha Centauri. Once you start playing, you cannot stop. Not very graphical, until you get to a climatic part. Same concept as Civ II and Alpha Centauri. New factions. New technology. Great game!
