Civilization II: Test of Time

Civilization II: Test of Time, released in 1999, is a turn-based strategy game similar to the best-selling game Civilization II. Test of Time's central innovation was the addition of multiple maps and the inclusion of two campaigns concerning science fiction and fantasy themes.

Test of Time includes an exact replica of the old Civilization II campaign, with only a few minor changes. Cosmetically, however, it looks quite different, with all-new art and animated units. Test of Time also offers the option to undertake the Extended Original campaign, which is identical to the original except that the "pink" slot for a civilization is occupied by aliens on Alpha Centauri. When one builds the Alpha Centauri spaceship, instead of ending the game, it unlocks a secondary tech tree and allows the player to battle the Centaurians.

However, on all versions, the "red" slot for a civilization is always occupied by the barbarians (religious fanatics, barbarians, and guerillas).
