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

In my humble opinion, it would be good if each column had its own color scheme (for example, like in the original, the entire third column is red for Humans, and blue for the Elves). That is, all alternate upgrades should be in the same color scheme – you currently have the alternate Simurgh in green, and the alternate Djinn in dark purple; I already suggested changing the alternate Simurgh to a different color – green is too Necromancer-like.
P.S.: Following this logic, you could repaint the alternate Djinn green instead of the alternate Simurgh, but that's nonsense in my opinion :D

Ah yes, I almost forgot – the alternate Djinn in the video looks good :)
