The most challenging maps for you.

We've already reworked it twice. In the end, we got versions 4 and 5.

I think if we were to redo version 3, the most successful approach would be to keep the same gameplay style, the same factions, the same turn order, and the same balance. We could add 1-2 races.
Improve the graphics, make the AI smarter, and make the AI in battles very strong, up to the level of a strong chess player, depending on the difficulty. Then the game would be priceless.
