It’s a thought I had over dinner (ironically enough) that I thought would change up the way that players go about their days and how they prioritize things. Basically, the more hungry you are, the bigger this trait’s penalty would become, and eventually the character becomes uncomfortable enough that they must eat something, because they feel like they have to, both mentally and physically.
When you’re full, you get a “Satisfied” buff to mood, which is negligible by itself, but a small something. If you’re neutral, you get a tiny debuff, simulating the nagging sense in the back of someone’s mind who has a food compulsion - but when you’re legitimately hungry, that penalty starts to build up. The hungrier you are, the worse it gets - and when you become “very hungry,” the penalty hits that magical point that makes it impossible to craft or study, where your character forces you to prioritize eating above anything else. At the wrong time, this could be a very bad thing indeed, and will make players think twice about going anywhere without your meals planned out or preparing rations ahead of time. It also makes binge studying and crafting more complicated, maybe incentivising players to find alternative methods to do the same thing if it’s a long, drawn-out process.
It won’t kill you, but it’d definitely change how people play and provide a small challenge in itself. I thought it would be pretty interesting.
