The rules of the games will use gauges for Health and Stamina. Cards are for the characters, combat and defense moves, weapons and loot. I made a prototype of the character control panel, with the gauge using gears. Characters can have a maximum level of 50 (number of gear notches) in health/stamina. Attack and defense moves will make the gauge lower according to the weapon and move used.
Made a little mistake on the board: the gear must turn in two direction, but the way I put a plastic strip block the gear in one direction only. The printed gauges on the picture are for a previous try, new print with a smaaller size to come. Cheap plastic gears from radio-controlled model cars.
