Hey Ralzar, I've been really enjoying this mod a lot in recent playthroughs and wouldn't go without it. I've always used survival mods in Morrowind and Skyrim. It adds extra necessary depth to gameplay by forcing you to plan ahead with extra layers of clothing and fresh food and water before heading out on your journey. I've died a few times already by not wearing enough in cold weather or not having a filled waterskin available in hot climates. You learn quickly to prepare.
I have a few suggestions that may be of interest. But I may also just be ignorant of how the mod works or what is actually possible to implement within DFU. These are just ideas and suggestions and may not reflect your vision for your mod, so no worries if you don't want to implement any of these.
Curious if there were any thoughts on expanding the Thirst mechanic. It's fairly limited atm, being that it's only function is to help keep you cool in hot weather/climates. In RL water is essential regardless of where you are or what temperature it is. IMO water should be just as much an essential resource as food, if not more so. Sure, in hot climates/weather you'll need more water than other times, so you'll keep a few more waterskins handy and keep them filled best you can.
Water also could serve multiple purposes depending on water temperature. Normal water will be Cold and that would help keep you cool in Hot temperatures. But Hot water (water heated via campfire) could keep you warm in Cold temperatures. Hot water should maintain it's temperature most the day since we can assume you are keeping the waterskin well insulated under your cloak or in a pack.
We can assume that the Tent Canvas and Bed Roll are rolled up together, but the Campfire should probably be a separate item somehow. It would add an extra resource item that has very limited uses, again forcing the player to pay attention and plan ahead. Also, since it would be a separate item to set up you could add specific campfire functions like warming yourself up, heating water or cooking food. Having the Tent/Bedroll set up along with the Campfire will keep you warm while keeping you safe and dry. Somehow the mod will have to detect whether either part or both is set up. If that makes any sense.
I know it's hard to make new items in DFU and I'm ignorant on how that all works. I wasn't sure if currently all you need is an existing graphic in order to create a new item, because there is one graphic that is just a stack of Wood, maybe could be used to represent the campfire item?
Putrid Food Items:
A suggestion, if at all possible, that if food deteriorates at or beyond 'Putrid' it will automatically disappear from inventory/container/loot-pile. Even putrid food doesn't have a use and wouldn't want to eat it at that point anyway.
Anyway, Thanks Ralzar for creating the Climates and Calories mod.
