In game it seems that Hunger is both a measure of available energy AND the feeling of hunger. Which feels wrong to me, you could be the fatest man alive you will still be hungry at least 3 times a day ( and probably more than that because obesity tend to disrupt the way your body senses the available energy).
The feeling of hunger is a cyclic thing that operate on at least two time scales. On a short time scale it’s regulated by the time of the day, the fullness of your stomach and the amount of calories you ingested, on a longer time scale it’s influenced by the amount of fat stored in your body.
The way the game works right now hunger is just a measure of what you last ate, it feels a bit like you’re always starving, or like every calorie intake you have is consumed.
Sitting still reading book all day long can also be a big part of a play through, and yet even if you feast in the morning and do nothing of your day you’ll be famished by the end of the day. It feels especially weird with the extrem metabolism mutation, where does all those calories go ?
I’m not sure I made my point clearer but anyway this should be mostly fixed by the introduction of the starvation variable.
I guess the main thing I meant is that Hunger is an approximation of your available energy and not your actual reserves
To get back on topic it would make more sense if matter consuming action would actually pull from your reserves : Starvation stat. And the exhausting ones should pull from Stamina.
