Upkeep

You might say: maintenance, unit support

A per-turn cost for keeping units, buildings or cities.

What it does

Is a drain that stops the player from keeping everything they have ever built.

Ask

What share of income goes to upkeep, and does it rise faster than income?

Trouble

Too low: huge standing armies. Too high: the player cannot afford to build.
