I have a few questions for you:
1) Will the mod be supported after its creation, and will it be adapted to work with the EWA mod (specifically, will the creatures in the Fort on the Hill be changed to unique creatures not available in the town)?
2) Is there any way I can help you (suggest an idea, find a mod that could be integrated into RTF, create a video about the work done)?
Now about the mods:
I have replacements for almost all the towns, sometimes even two (mages can be replaced with elementals in Arcanum and Stronghold; Demons can be replaced with another version of Demons or with elementals; Orcs can be replaced with Swamp or with some kind of strange creatures resembling Haven; Dark Elves can be replaced with Nexys; Light Elves can be replaced with Conflux; Humans can be replaced with Pirates; Necromancers can be replaced with another version of Necromancers; the only town without a replacement is the Dwarves)
