Really hoping for these at min with base (or added with 1st DLC)
CHEMS from NV
FWE/IMCN/Project Nevada -- adds the 3 basic NV hardcoe needs PLUS more complex needs and environmental interactions these mods added PLUS Toilet Paper mod (and ability to bathe/get dirty)
Ambient Temperature effects synched with Weather effects -- so your PC can react to temp changes in their environment. Being cold should induce hypothermia (the way Chesko's Frostfall in Skyrim works). Or being overheated should affect thirst, ability to wear power armor/heavier armors, amount of layered clothing your PC wears, affects their vision, cause them to faint/pass out from heatstroke etc. Basically their combat abilities and crafting skills should be affected for example
Skyrim's Frostfall & Wet n Cold mod exposure penalties -- now that we know it can rain, have radioactive rain so your character can get themselves and clothing soaked. Being cold and wet should have combat and crafting penalities. Should encourage your PC to eat/drinks nourishing foods to keep their stamina, health and endurance up
Skyrim's Battle Field & Injuries mod. Pipboy already has a base fundamental design of this. But it would be nice if Beth still gives us the option to heal PC wounds over time. But difference here is that if this is like Skyirm's BFI mod, then your PC can and will ultimately die of their more serious injuries if not treated. You should be able to craft a variety of bandages, medicines etc using the CHEMS mod and other stuff you salvage in the wasteland.
Portable: Backpacks, stove/grill, water purifer, bedroll. Backpacks should add ability to carry weight. Hoping this would work immersively like Chesko's update of BlackWolf backpacks. And come in a variety of textures.
Better variety of pre war clothing (like the Spice of Life mod in NV) to add variety to the traditional vanilla prewar business/casual attire NPCs wore in NV and F03. But these need to be sold by specifc vendors in certain areas. Which force you to explore map.
More mannequins at your vanilla safehouse. At least 2 dozen mannequins. Now that we can build our own settlements with Beth's RTS version, then theoretically, this may be possible to construct additional storage rooms/armories separate from your home in the new setttlement towns
Fluffy stuff: working motorbike, car to compliment the working vertibirds and power pack we're getting. Would be great to salvage metal scraps and parts for a vehicle like a bike/car and put that together from scratch at the workbench
Cannabis mod (which beth would never add but would be nice if they added some sort of hallucinogenic plant harvestable your PC could ingest and sell to NPCs)
Alchol -ability to craft/brew this as ingestible, use for crafting weapons (like being able to add poisonous ingredients then adding that to a dart gun) etc. Then be able to sell it to NPCs or attack/assasinate them with it.
