Built-in autosave feature (for the TE version).

The tax is specifically designed to balance the game. That is, if one player receives a lot of power (e.g., many dwellings, consulates, hives, or skeletons for Necropolis), they will have difficulty with their economy. Therefore, in the mid-to-late game, it is necessary to build up the economy to compensate for the tax.

Another idea is to introduce a tax on dwellings and double-builds, something like 10% per day of the value of all bonus structures (dwellings and repeated castles/towns) – to make it more difficult to achieve an advantage in power.
