I finished Sid Meier's Alpha Centauri on the highest difficulty. Since i tend to not finish any game which is not a hardcore story driven RPG that was a feat for me. And I got told it actually is a feat on the highest difficulty. It was a race against time while the Spartans closed in on me to finish the Voice of the Planet and wiiiin! Oh sweet victory! Have I ever felt that way again before I defeated Ornstein&Smough alone? I think not.
