Heroes 5.5 WarGame Edition - Tactical Edition.

There might be other figures (depending on the implementation), for example, building costs could be 6 times cheaper in terms of gold and 3 times cheaper in terms of resources (instead of 10 and 2.5).

Regarding the "burnout," the purpose of introducing this mechanic isn't realism, but rather to increase the importance of the economy. The classic gameplay involves spending all resources, including gold, on city development in the first few weeks, with minimal unit recruitment, and only recruiting the entire army closer to the end.

Now, the idea is that if you fall behind in resource acquisition and fail to build the necessary structures within a week, you effectively lose production capacity and part of your army. The same should apply to gold, so that the player is encouraged to spend both resources and gold in a balanced way. A shortage of gold should be as detrimental as a shortage of resources. You can't just say, "I'll build housing for all these dragons in week 5, and they'll have the same growth rate as if they had been there for those 5 lost weeks, because I eventually gathered enough resources for them."

As for the suggestion to limit the maximum basic growth to 6, this will essentially have no impact on the game, as all units can be recruited within 3 weeks, especially since the entire game lasts less than 3 weeks.

Imagine a strategy game like Starcraft, where you build a lot of production buildings, but you don't have enough resources for constant production. And what, will all the units just accumulate on their own, waiting for the appointed hour when you recruit 500+ warriors at once?
