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

regarding "Might and Magic," I'll say this: these are dwarves, true gods of blacksmithing! if they need a blade for hacking, they'll simply adjust the center of gravity, and sharpening this blade on both sides is child's play for them.

as for the variety of troop types, I decided to explain it this way: these are troops from different clans, the most effective units from all over the country! bears are bred in the clan of dwarf-druids, infantry comes from the privileged nobility (they exist everywhere), archers are trained by the gunpowder clan, golems come from the mechanical city, and so on.
