i dont have access to that computer right now, but i remember the key ones for the wilderness survival were the old classic combo of frostfall+campfire (with all the overly pedantic and punishing options on), but with sunhelm for food/drink/exhaustion. and a no fast travel mod and a deadlier combat mod (smilodon i think), and a slower xp mod, and a less suicidal wildlife mod, and most of the simonmagus overhaul mods for perks and alchemy and cooking and spells etc. and an economy mod and loot scarcity mod so i wasnt drowning in cash and fancy loot. and immersive spell learning + dinos spell discovery + grimoire so i could craft/study spells for a few hours before sleep at a campfire or an inn, or spend whole in-game weeks at home in research while doing my crops and herbs and alchemy and crafting and woodchopping and cooking and arranging my spellbooks etc. and i remember tel jerdein was the name of the cottage and its unbelievably cozy and nice for a wizard, sitting under cover on the top deck on a rainy day with my plants and reading spell books, looking out at the misty valley.

and yeah a tonne of graphics mods but definitely the most impactful was somehow getting rudy enb to work on linux, holy crap what a difference but it seriously hurt my pretty decent computer. cathedral grass, cathedral weather, majestic mountains, smim, relighting skyrim, and skyrim 2020 textures were the other main ones i remember.
