It would be cool if monsters dropped money. For example, if you killed liches, you could get an artifact and also receive 258 gold for the victory, which would allow you to buy a building faster.
Also, it would be great to have many diverse quests, so that the tavern would offer quests, for example, to obtain a certain artifact. You bring the artifact, enter the city, go to the tavern, and you receive a reward in the form of experience and money.
I know that the game would then be more similar to an RPG.
but it would be more interesting.
to immerse yourself in the game, and not just accumulate an army, kill the opponent, and that's it...
