The ones in red are for sale. I would like to keep the ones in yellow, but they're for sale if you pay more.
the number '15' is the cost
where i say '5t', That is 5 turns worth of the structure's highest production. For example, if you upgrade the city to level 4 and get 'x' resources per turn, i expect to receive 'x' resources every turn for 5 turns. If you upgrade the city again, i shall recieve the difference. (If income was initially 5 and i was paid 25 resources, then upgrade and income is now 10, you owe me another 25 resources).
All prices are negotiable but not the zones that i'm selling. Those are mostly decided for now.
