FEDERATION & EMPIRE
Federation & Empire is the classic game of galactic strategy. You command the Mighty Klingon Empire, or the economic powerhouse of the Federation, or maybe the Romulans or Gorns or Kzintis or Tholians or Lyrans or Hydrans or ... you get the point.
Once you have assumed your duties as military commander in chief, you collect taxes and spend the money building starships and bases and colonies, or converting ships into special mission variants.
Then it's off to war and conquest, as you drive your powerful battle fleets into enemy space to take their planets away from them and call them your own!
