A Heroes of Might & Magic 2 total conversion mod and scenario for Civilization II MGE.
Metro has replaced the entire Civ2 throne room with HoMM2 castle screens broken up into puzzle pieces. As each area is upgraded you'll go through several castle types. So if you choose to upgrade one particular area a few times it will lead to some rather funny results and mixed matches lol. While we would have loved to have done a castle with individual buildings being built (similar to what Tom did with his awesome HoMM3 Civ3 mod) the positioning of objects in the throne room is hard coded and not something we can access to tamper with. So castle image puzzle pieces was the best we could do!
