WOTC invent buildings

Each nation has its own set of buildings, invented by YOU, the controlling player. You start the game with no buildings at all.
*Follow this sheet to invent a new building
** A building can only be built on the next round after its invention (never on the same round / action)
*** The stronger the building is, the more it will cost. Each attribute you add to the building costs an "Ingenuity point"(see sheet below), the more ingenuity points you invest - the higher the price for it is going to be.
**** The maximum amount of ingenuity points you can invest equals to your nation's level, and additional point for every 2,000 population (example: a nation level 4 with 2,200 population can invest up to 5 ingenuity points when inventing a building)
