Sometimes you’ve gotta’ spend a lot -and I mean a lot - of time doing something. Maybe you’re processing that big damn pile of veg you just harvested, or breaking down all that sweet loot from your latest town raid, or poring over that neat textbook for knowledge: whatever the case, you’ve got to devote quite a chunk of time to it, and that means dealing with all the hunger and thirst and fatigue you’ll rack up during said period. Sure, you COULD do it in bulk in a few goes, but then there’s all the penalties to productivity racked up in the later stages.
Rather than having to micromanage your basic needs during these productive times, what if you could dictate specific items to be used when the appropriate conditions arise, such as when you cross the threshold from mere desire to serious deficiency? Say, three different slots for for hunger, thirst and fatigue, which use a text-line interface similar to that for AutoPickup entries: when you’re in Safe Mode and a need ticks over to serious deficiency, it checks your inventory for the item specified for use and Activates it. You could thus set up something like Meat Jerky and Clean Water and Caffeine Pills, and as long as you’ve got ample stocks of those items you’ll be well set to keep truckin’ on as need be.
And on the topic of basic needs: what about adding numerical representation of them to the Aware trait as well? Needs are even more quantified than health is, so having an exact idea of just where you are hunger/thirst/fatigue-wise would be equally as useful as for health, if not even moreso.
