Some civilizations that were considered for The Conquerors during development but didn't make it to the game include the Incas, (because they would have required either an exclusive set of buildings or doing the American one too generic, plus the developers already had difficulties trying to make 2 civs with no horses distinctive enough) and some East European nations such as the Russians and Polish which would have got another unique building set.
The developers considered giving units multiple attack modes, but decided it would add more frustration than it was worth.
