Population - Urban Systems -------------------------- Andy Merritt's House Rules The following rules give players a bit more flexibility in trying to keep their population growth roughly where they want it to me: 1) Landing on a Free Port: You can EITHER buy any resource units upto $1200 value OR Draw a +/- card. 2) Add two OPTIONAL MedU and Edu's to the very bottom of each population pyramid. These don't have to bepurchased, but can be if desired to correct the population growth at the end of the game.
