Do you want to see survivalism gameplay? Namely, hypothermia, realistic needs and hunting? There are mods for this, but I'm waiting for the patches to be updated for the latest version, as the new Frostfall mod has significant performance improvements over the currently patched version. This will mean the possibility of freezing to death, starving to death etc.
Secondly, what kind of character would you be interested in. I have a couple of ideas, and I'm pretty open to any of them, as all should be end-game viable. Basically, your choices are nightblade (stealth and magic), paladin (shiny armor and good magic) or spellblade (fire magic and conjuration and swords). I'll come up with backstories and motivations later.
I would say Nightblade, as I'm a sucker for the stealth classes, but if it is deemed too overused, I would go with spell blade, both since it would likely be really interesting and to remind myself to branch outside of stealth once in a while.
As for survivalism, while I am on console, so no mods for me, I am interested to see the depth it adds and its affects on the rest of gameplay, so go for it
Some Youtube videos: Hunterborn and Frostfall. The Hunterborn one is quite out of date, the alchemy and equipment overhaul it provides is now quite extensive.
The idea with a Spellblade would be to use Destruction at range, Conjuration for Tanks, Alteration and Light Armor for defence, swords for melee. Probably also a bit of alchemy and enchanting, but I have a mod, Honed Metal, which allows me to approach NPCs to do my crafting and enchanting for me, provided with the right materials and enough money (much like Morrowind).
Frostfall is currently, save or don't, IIRC, and it doesn't currently seem to recognize cloaks and scarves added by other mods that it used to. It feel like it's a whole lot harder to stay warm.
