I would love to do some Bloody Bill and Quantrill type skirmishes.
I and a friend have put on 28mm Wild West/ACW skirmish games using Brother Against Brother rules. These games are for 8 or more players and include post-ACW (renegade) Confederates, Quantrill and his band, Bloody Bill and friends, Apaches, U.S. Cavalry, Imperial and Republican Mexicans and French (in Mexico, American Southwest). The Quantrill and Bloody Bill figures are all from Wargames Foundry (in case you are lookiing for those figures).
These games include a publo town with a steam train, railroad tracks, water tower, and around ten buildings with corrals, etc.
The French are usually trying to sell the Confederate renegades a rail car mounted heavy cannon with the train for stolen gold. The Imperials and the Republican Mexicans want the gold. Quantrill and Bill want the gold. The Apaches want the horses and cattle in town and guns and gold. The U.S. Cavalry wants the Confederates, the cannon and the gold. All the players have a different agenda/objective, alliances are encouraged between players with a lot of cut throat activity seen between players.
The train arrives early and the attacks begin at random from random/assigned directions. This game is played on a 6' by 12' board of southwest terrain. I can upload some photographs of one or more of the runnings of this game scenario if there is interest.
