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

I like both options, especially if the upgrade differs from the base version in terms of color. But we need to decide where the lizards will live (in deserts or jungles/swamps). Because the choice depends on the color of their skin :D
However, the helmet and the head itself make them more suitable for the first option. Desert lizards would suit the head of some kind of skink (or Australian moloch).

And in any case, the red option is too poisonous in color. It is better to change it to some kind of crimson or cherry (as an option). However, then the desert lizards will be too similar to the Cabirs... this is not suitable.

In short, I like the first option a little more.
