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

That’s exactly what I thought.
By the way, maybe we could replace the current merge outpost with an elemental dwelling from the original game?

It's possible; at least, I'm for it.
I also had an idea for a new infantry unit for the Lizardfolk.
The old one was based on a swordsman, but this one is based on a monk.
