Did you know that you could store up to 50000 units of energy in former versions of DayZ?
You probably all noticed that you can keep stuffing food in your mouth without any penalties. I do not know what the current number is, but regardless, the result of the number having been that high, is not only everpresent but even exaggerated, as the player doesn't have to vomit (or only after an insane amount of food and drinks). YES, vomiting used to be a thing and an important limiting factor. Anyways here is, what problems I have with it being the way it is right now:
1. It's partially immersion breaking, clearly
2. It requires less planning ahead by the player
3. It messes with the loot table
The first two ones are pretty self explanatory I believe, but I will touch a little closer on that 3rd one:
If there are no penalties for eating everything you find, guess what you will do. Exactly! And so, as a result, if an area was picked clean, there won't be any food left. There will never be a moment where you are like: "Ok, my stomach is full, my character seems pretty well energized and I have no more space in my backpack....aah whatever I still have two cans in my backpack, let's just leave this one." - NO, right now people will obviously pick up everything and eat it right away, until maybe at one point they feel like they have already eaten so much they don't need to, for another 7 or even more hours (the sky seems to be the limit).
So here's my proposal: In my opinion DayZ does NOT need a crazy detailed metabolism system such as the one SCUM has implemented. All we need is proper stomach volume and digestion times (emptying the stomach gradually, so you can eat more). When you push past that stomach volume by a certain amount, your character should have to vomit (just like it used to be in the legacy version) AND we need a cap that makes sense, for how much energy your character is able to take in total, to avoid the situation where your player will never have to eat again, before he dies 48 play hours later!
Anyways, thank you for reading, feel free to VOTE and share your THOUGHTS in the comments, where I will be happy to discuss it with you.
