I have some idea’s regarding running and it seemed too in depth to post in the needful additions thread.
-Have foot, leg and torso encumbrance slow running down more or increase stamina drain. Running in jeans is difficult compared to shorts.
-Have high temperatures drain stamina. Just walking in 100 degree weather is exhausting.
-A trait that gives immunity to the lost breath debuff and allows you to continue past red stamina in exchange for damage to torso. Running yourself to death is possible.
-Have carried and dragged weight effect stamina loss. I imagine running with 30kg of Equipment would be tiring at the least.
-A trait that decreases the speed penalty caused by pain.
-A sprint mode that would not work with rollerblades, be affected by changes in direction, take multiple turns to reach speed, and cost 4x as much stamina as running.
-Recovering stamina increases fatigue, hunger and thirst.
Hopefully these will add to the game experience and difficulty. Let me know what you think.
