I would assume its a 1k upkeep cost per plot. Or maybe its 1k base and then x for every plot?
We have already decided on what the cost of things will be.
Towny Price: 150,000
Towny Upkeep: 1,000
Nation Price: 2,500,000
Nation Upkeep: 10,000

Is this all you've decided on?
What about plot price + the increase in upkeep? (If there isn't an increased upkeep for additional plots, you're going to have some extremely large towns.)
Nation upkeep for additional towns that join?
That flat upkeep rate is going to be redundant compared to the price of a start up of a town. I'm sure people will find exploits to gain money quickly. In this case, you obviously don't want 100 towns if your playerbase is 300. Towns need to be more expensive as more are created to prevent the issue previously where everyone wants to own and run their town, but then realize it's a money sink without players to join it.
