We definitely wanted Dead State to be about survival, and we needed a resource to reinforce this. Allies need food every day. If they start to starve, it causes morale problems, which can start to impact the ability of the shelter to function. Having to go out for food is risky, but necessary. For gameplay mechanics, it prevents the player from just turtling in their shelter. It also organically raises the difficulty of the game – more allies, more food needed, more (and farther) locations need to be reached to gain access to food (and the chance of running into more hostile groups). Then you factor in luxury items to help with morale and fuel for generators and parts for shelter upgrades and there’s an awful lot of reason to go out and search for more people to help. The more you have, the more you need, and so on. Also, food and other items can disappear over time due to the looting efforts of other groups, so the game gets a bit harder as it goes on, and forces you to start taking risks, like trying to loot riskier areas or take on larger groups for their supplies.
