Elite was for years my favorite space game. The mix of hunting and trading was the best...even more fun was to play with a friends so you can play more or less 24 hours (ok the most we played was somewhat 12 hours...but it was fun :D )
Civ marked another milestone in Gaming History. The concept and success of round based building games is more or less founded on games like Civilization. Ok at a point it became odd, when u had nukes while your neighbour civ just invented the muskets....but hey...life is not always fair :D :D :D
