No, but it would be interesting to create a game in the style of Heroes, with battles, and so on, using the engine of the fourth game! It's interesting to think about what we (Heroes fans) could achieve. War of the Griffon isn't quite the same. We could beautifully implement the disappearance and restructuring of factions...
But as it is...
I can suggest the following:
-The Dwarves, together with part of the Elves, launched a rebellion and left to form their own kingdom. However, due to greed, they decided to betray the rebellious Elves.
-The Elves, in turn, formed an alliance with the Swamp Orcs and went to the Dungeon to reclaim territory for their state. In the end, they won and stayed there.
-During a council meeting, one of the mages, after his troops were defeated by a group of skeletons and zombies, suggests using "airspace" to protect themselves temporarily from ground units. At the same time, the Necromancers are oppressed.
-The Orcs simply join other cities and disappear from military operations. And the dissatisfied groups are simply killed by other races.
-The Elementals - it's clear, a rebellion, a revolution, and an inability to create a normal kingdom.
Here are a couple of ideas. I understand that it's not very good, but it needs to be fully developed. Then it would be better. P.S. I can't come up with anything for the Orcs because they are the strangest race.
