RTF is a global modification that replaces all towns in the game.

2) I had an idea to create not a global mod that replaces entire factions, but a collection of small mods that replace individual units. This will allow players to more easily customize the gameplay and faction to their liking. For example: I don't like the zombies and undead in the Necropolis, so I replaced them with Mummies and Black Knights. Let alternative units be available for all tiers. This will result in a complete faction replacement, with the ability to keep your favorite units. (I hope I described the idea clearly)
