This may be a bad time, given events going on in the US right now, but I think there could be a workable firefighting game based on Axis and Allies. One side are the firefighters, which “attack” into hexes that have fire units in it, while the firefighters also have aircraft and fire trucks acting like tanks. The “fire” side simply possesses fire units attacking the firefighting side, trying to take territory to make more fire (it takes place in a forest, so a fire taking wooded area obviously is able to increase the ability to make fire units). The fire’s goal is obviously to take the firefighters’ “capital”, while the goal of the firefighters would be to destroy every fire unit in a short amount of time.
Thoughts?
