Pot That Fellow, Somebody Colonial Rules
Pot that Fellow, Somebody is a set of free miniatures rules for the colonial era. Author RP Bergman writes:
These rules are intended to fight Colonial quasi-skirmish level games with multiple players and 2-3 units per players. Colonial players includes Europeans, Americans, and any other modern power with advanced military technology. Native players include includes Zulus, Dervishes, Pathans, etc. Units are rated according to Morale Quality, Melee Skill, and Firearms Skill. The Morale of units degrades as they lose leaders, take casualties, suffer from the heat, or fail to take action during the battle. Eventually, even the best unit may “run away” to live, fight (and die) another day. Units take a variable number of actions each turn, with the better quality troops having a higher chance of taking more actions.
Warbots Robot Combat Game
WARBOTS is a game for 2-6 players using the Z-bot toys from Micromachines (or any other cartoonish robot figures). It was originally inspired by the old Metagaming MicroGame “Rivets” by Robert Taylor.
IN THE NOT-SO-FAR FUTURE…. Man built the Warbots to fight his battles for him, but eventually the machines turned on their masters and wiped them out. However, computer-controlled factories continue to manufacture the killer ‘bots and send them out to be tested. Every afternoon at the Disneysoft military/industrial/ entertainment complex, the latest line from the company’s Warbot™ Urban Peace Squad (WUPS) roll out for another demo, with two teams facing off against one another.
