AnotherGame is a mod for ToE 3.1.

Dwellings are like mines. Most mines, especially in the late game, are practically unnecessary, depending on the situation. And this (the fact that objects play a role depending on the situation) is a perfectly normal part of the gameplay in Heroes 5.

Unlike non-native dwellings, mines are captured much earlier ;) Hmm... For dwellings - conversion, for mines - improvement. The procedures are different. If we were to make improving dwellings as a bonus, then they would already be comparable to mines, but as it is, considering the different procedures, they are different not only in their application but also in their result.

I had an idea for alternative buildings in the city. For example, either a warehouse or a capitol. In this case, the cost of improving mines would decrease significantly, while the cost of the warehouse would increase.
For example, the price of upgrading a mine without a warehouse = 5000, with a warehouse 1500.
