I'm sure people here probably get tired of seeing this but... I just got Skyrim for PC

These are the mods I have so far:

unofficial Skyrim patch

dawnguard

unofficial dawnguard patch

hearthfire

unofficial hearthfire patch

Dragonborn

unofficial dragonborn patch

falskaar

Climates of Tamriel

HighRes texture pack 1

HighRes texture pack 2

HighRes texture pack 3

SkyUI

When Vampires Attack

Realistic LIghting Overhaul 1-5

Climates of Tamriel falskaar patch

Frostfall

A quality worldmap

SKSE

BOSS

any other mods I probably 'should' get that will make a noticeable difference, keeping in mind I really don't want to change up the vanilla gameplay too much, at this point (don't want to use spell mods or enemy AI mods yet, or mods that add all new gear-still getting used to the vanilla game.)

Frostfall would change your gameplay a lot.

Personally, I would take out Falskaar, Climates of Tamriel, Realistic Lighting Overhaul, When Vampires Attack, and Frostfall.

So what you're left with is just bug-fixing patches and UI mods. Gameplay will be vanilla, but now with fewer bugs and a better UI designed for PC.

SKSE is a needed utility for a lot of mods to function correctly. BOSS will sort out your load order.

I can understand taking out frostfall, cause it makes a major gameplay change... Falskaar is just a new area that adds new quests doesn't really change vanilla game.

Climates of Tamriel, Realistic Lighting Overhaul just make the game look nicer

When Vampire Attack just fixes so that NPC's aren't getting killed off, was a pain on PS3. I also wanted to get When Dragons Attack mod, but couldn't find it on Nexus...

Basically I played the dark brotherhood questline, main questline, thieves guild questline on PS3. I still have a lot of Vanilla to explore and quests to do, just added Falskaar for if I didn't want to get into Dragonborn or Dawnguard quest, for a 'new' area to try.

On PC right now , my main interest is making the game look better, play smoother, and maybe some simple 'fun-factor increasing' mods. Any suggests are more than welcome...basically anything that will enrich my Skyrim gameplay, and a brief description of what it does

All suggestions will be greatly appreciated And ty for your time , on what is a very repetitive question in these forums.
