Hello everyone!
I suggest creating a mod for HMM 5, based on the idea of "Heroes of War and Money."
What makes it interesting is its difficulty, and this difficulty doesn't come from neutral creatures on the map, but from building structures and hiring creatures.
For example, to upgrade Gremlins, you need a hero level of 5 and 7,000 gold, 50,000 wood, and 50,000 ore for the building. In HMM 5, upgrading them requires 5 ore and 1,500 coins, and the building becomes available as early as the second turn. And so on with the other creatures. In HMM 5, everything is too easy to obtain; it feels like some kind of cheat was used, making everything simpler.
Upgraded Gargoyles: 50,000 coins, 30 mercury, and level 8.
Upgraded Golems: 30,000 coins, 50 wood, 50 ore, 50 sulfur, and level 10.
At the beginning of the game, you'll only be able to use Gremlins and Gargoyles. For "simple" Golems, you'll need to wait for a certain hero level, I don't remember which one, I need to check.
In general, it's all great, and it's turning out to be interesting!
