No love for Sid Meier's Alpha Centauri? The greatest of all the civ games? :( I am a sad panda. I play SMACX every now and then because the writing and world building are fantastic. The original xcom with the fan patch that lets you actually change the difficulty (there was a bug in nearly all versions where when you changed the difficulty it didn't change) a still a great game although I think Xenonauts has finally replaced it.
