Another game, Unveil, started with me in desperate need of food and water. There was a river nearby, blocked by a line of trees, so I began walking to find a gap. I died of thirst before I could even reach the river, less than thirty seconds after starting the game. When I played H1Z1, I had a slightly different problem. It was easy to find food and I never found myself in danger of starving, but I still had to eat almost constantly because my food meter depleted so quickly.
Systems get tweaked during development, and there's a lot of work and fine-tuning before the perfect balance can be found. A lot of Early Access survival games make hunger and thirst too demanding right out of the gate. Begin with a system that needs to be used but isn't overly punishing or you might chase new players right out of the game. Later, start tweaking it to be more challenging.
