character doesnt even eat.

If you get the Foodtorio mod, not only can you eat, you must eat. It introduces a hunger and nutrition element, requiring this mod as a dependency. And to me, it just makes sense. You're supposed to be a human, not a robot, that crash landed on an alien planet, stuck for days as you design and produce a way to get off the planet. Why wouldn't you need to create a farm and eat food to survive? Of course it's all optional since this is a game and everybody has a different opinion of what they consider "fun", but I wanted to bring it to your attention in case it's something you are interested in.
