I followed the full builds of u/Snigaroo for both KOTOR 1 and 2, including all the optional mods.
(The only mod from his list I didn't use was Handmaiden for females for KOTOR 2 as apparently she still refers to the PC as male, thus I find it to be slightly immersion breaking)
On top of that I added roughly 7 mods after checking with Snigaroo (1 of which replaces another mod in his list)
KOTOR 1
Darth Bandon Head Reskin (Darker Version) Used this because the guy looks very generic IMO without it (Bear in mind I played KOTOR 2 first, so Sion was the mark for the intimidation antagonist chasing the PC)
KOTOR 2
SWTOR style HK (Everything is defualt, except I used the optional Hybrid HK variant) Definitely the most controversial mod on the list by far, I didn't like the HK reskin in the mod list, and found that I preferred the look of this mod, subjective of course, There are a number of reasons why I like this design more, but essentially its just aesthetics.
JC Saber Workshop Rather simple mod conceptually, allows you to deconstruct lighsabers for parts, as well as put those parts together to make new lightsabers; If I can build a lightsaber in KOTOR 2, why can't I deconstruct one ?
Improved Widescreen Experience I used this mod and the above mod to fix the resolution issues for my game; The reason I needed too, was because despite the Patch on steam, I couldn't use Lightsaber Hilt mods in Snigaroo's list without rolling back to the pre-update version of KOTOR 2 on steam.
I also used a robe replacer mod for KOTOR 1 and 2, I won't post them because those mods are just the aesthetic of robe I wanted, but essentially they were just reskins for existing robes as well as the KOTOR 2 robe replacer also adding armored robes to a trader on top of the initial reskin.
