I think a good point was made... play vanilla for a bit and find out what you don't like.. find mod's that change that.
Other than these ^^ most are really personal choices...
I added those plus some of these are my 1st batch of downloads ( I used Satellite interent.. plus cell phone as a hot spot. ) so my data was and still is limited
LOOT...though NMM has it
NMM
Minimal HUD ( which different than I-Hud ..personal choice )
Alternate Start- LaL
A Quality Wold map
Immersive Armors
Racemenu ( and everything needed for it )
Wyre Bash
UNP Dimonaized
Dog's of Skyrim
No More Blocky Faces ( many face and body meshes now have this)
Convenient Horses
. I spent 4 yrs playing on 360... when I got my PC.. I already knew exactly what I wanted to change and which mod's I wanted to get... Some thing's I picked as 1st batch were not only because I wanted them...but file size.. they errr fit into the jig-saw that was my data limit... I added a bunch more when my data cycle renewed.
One thing you may want to do is go onto the Nexus and look at the Body/ face meshes and what you like the most... then check the armors... I mean their is no reason to load that CBBE only armor... if you plan on using UNP.
Also make a list of the mod's you want and their requirements... check those out.. then check out any requirements the requirements need... Trust me, it beat's thinking you have every thing you need... only to CDT on load up... and have to come and ask... then do a step by step check and research of each mod.
