Heroes 5.5 WarGame Edition - Tactical Edition.

I'm working on the economy (building prices). Here's the concept: Basically, all cities require at least a moderate amount of gold, ore, and wood. These are the basic resources. Additionally, each race has specific resources that they heavily rely on. The requirements for non-specific, rare resources are low (usually only for the Mage Guild). Specific resources (resources for level 7 upgrade in parentheses): Castle (Humans) = gold, wood, and ore (crystals) Rampart (Elves) = wood, crystals, and gems (gems) Academy (Magic) = gold, sulfur, and gems (gems) Fortress (Dwarves) = ore, sulfur, and crystals (sulfur) Inferno (Demons) = wood, mercury, and sulfur (mercury) Dungeon (Dark) = mercury, sulfur, crystals, and gems (sulfur) Necropolis (Undead) = ore, mercury, and gems (mercury) Stronghold (Orcs) = gold, mercury, and crystals (crystals) Most profiles are built on the principle of: 1 basic resource + 2 rare resources, corresponding to the native schools of magic (mercury = dark, sulfur = chaos, crystals = light, gems = summon). The exceptions are: humans (demanding all 3 basic resources), orcs ("borrowing" the magic profile from humans - crystals and mercury, light/dark), and Dungeon (demanding all 4 rare resources). All profiles, except for Dungeon, intersect in pairs with only 1 resource out of 3. This means that any pair of different cities heavily requires 1 common specific resource, while a pair of identical cities heavily requires all 3 specific resources (much more difficult to build). Dungeon intersects with all others, except humans, in 2 specific rare resources; and it has no intersections with humans (an ideal pairing, except for morale). Building prices will be focused, with no more than 2 types of resources, in addition to gold. With the exception of the Mage Guild, and possibly other very rare buildings. The fact is that there are many more diverse strategies for obtaining specific resources than there are strategies for "collecting a little of everything." Furthermore, with focused resources, the difference between different city building options in terms of cost is amplified.
