Here's my sketch for the final version of the Lionsgate City Underground board. The idea is a series of caves connected by tunnels. Players move between caves through tunnels, and can also block tunnels with their train cars. There are five kinds of caves: Mines, where ore is dug up, Towns, where it is sold, and the Mercenaries' Guild, Sheriff's Office and Vault Exit, each of which has a special function in the game.

My goal is to have some copies of the game for sale (or at least to play) at Vancoufur this year.
