If you love America, you through money in it's hole!!
3 players: Base game setup with $20.00 starting cash, 12 rounds, and 4 payouts. In addition, use only 4 of 5 towns available. exclude one of the size 5 towns (Abilene or Dodge City). This makes for a more interactive game by limiting corral and B/T board spaces.
4 players: (2 options)
Option A - $25.00 starting cash, 9 rounds, and 3 payouts. Shorter game.
Option B - $20.00 starting cash, 12 rounds, and 4 payouts. Longer game.
Base game setup meshes these two options into one but makes for a cash poor game. Losing a payout round and starting with $20.00 cash makes expensive B/T counters (Bank or Train) obsolete or foolish investments. Time is needed for these counters to work monetarily. At least 2 payout rounds minimal.
5 players: Base game setup with $25.00 starting cash, 9 rounds, and 3 payouts. Wallace's addition of extra actions for cattle, cowboys and gun fights accommodates for the shorter rounds adequately.
