Right now I am starting with the game. And the obvious first option is to made a board to play. So far I have made six 60*30cms boards. Base is 5mm MDF, with a second level raised over 5 cm wood. Roads are sandpaper. Paiting with a Neutral Grey spray, with drybrushed white and weathering with Sienna Brown. In the sides, everything I had in the dush bin (pieces of fruit cages, coffee stirrers, pvc pipes, pieces of wood from a wine case). They are modular and stockable, so far.
