This is an idea for a taxation-rebellion mini-game mechanic, useful for megagames set in agrarian economies where the peasants do not really care who is in charge, so long as they do not “tax” too much of the harvest.
Each tax region in the game gets its own “bingo card” with a grid of boxes. If control of the region changes, the player who lost control gives the province card to the player gaining control.
When a player desires tax income, they queue for the appropriate map GM’s attention and present the Tax Card. The player indicates which boxes on the Tax card they wish to strike out, and these are filled in with a permanent marker. The map GM then consults a master reference to check if any of the boxes struck out triggers a rebellion. This look up step is likely to be the most time consuming step in the process, so I am continuing to think of ways in which this process could be refined. Keeping the number of boxes to a small number, say a dozen, would be one way of managing the information. Another might be to draw the boxes in a pattern shape, making it a bit easier to visually identify.
As an additional modifier, some boxes do not trigger rebellion, but just increase the future strength of the rebellion. If a player strikes these, the GM can give them some feedback on grumblings of discontent among the peasants.
This might interplay with military actions, in that raiding a province is represented by harvesting tax in a just conquered province, and then leaving as the peasants erupt in rebellion. Some experimentation is required to determine a hard cap on how much tax a player can collect in one action, otherwise someone is sure to say “I’ll tax all 20 boxes right now thank you”.
Tax regions that are likely to be more rebellious could have more than one trigger box to start a rebellion. Some trigger boxes could be made conditional, such as “trigger rebellion only if tax collector’s capital region is more than X distance away”. Another twist could be a “insurrection” modifier, where if there are rebellions in adjacent tax regions when a player collects tax, then they must strike out an extra box without collecting revenue.
Conversely there may be options a player can implement to reduce the chance and strength of rebellions. Keeping a garrison in the province is an obvious one. Another is allow structures or organisations to be built (e.g. Palaces and Bureaucracies) that reduce the number of boxes struck out when you tax.
