So, for my RPG, I've decided I'd like to have some kind of survival system. Except, I don't want it to be a "eat every 6 hours or you die" kind of thing. What I'm hoping someone here will be able to help me with, is to create a system where you need both food and water (represented by vertical HP/MP-style bars on the far right of the screen) in order to travel. As you'd move across the world map, these bars would decrease (but water would run out faster than food- since humans can last longer without food than they can without water), and you'd have to stop off at a town or trading post in order to refuel. If a player didn't refuel, they'd pass out, possibly lose some money from people robbing them while unconscious, and waking up at the last town they visited, being nursed back to health at the inn. I feel this would encourage players to travel off the beaten path- going from Town A to Town B might seem easy enough, but you could run out of water before you get there, so instead you'd have to travel from Town A to Town C, before heading to Town B. I hope this makes sense!
