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

5 is almost done; for the Nags and the cities, only 2 creatures need to be created, and the Sea Elves aren't that difficult (unless they decide to make something beautiful).
The Voidlings also have a couple of creatures (riders and skeletons).
The Church already has swordsmen.

The Guards have already been visualized by [email protected]; it's difficult to come up with something new for the crossbowmen.
