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

Can you tell me who that lava guy with wings is?

Which guy are you talking about? I don't have any guys with wings, only lava dragons.

If you want to see who's in the mod, go to the first post of the thread; there's a link to the units individually. You can open them one by one and see which one is more interesting.

Or, check out the VK group; all the units are stored in albums there. There's a link to the group in the first post, or you can Google "RTF mod."
