It really is amazing how much work goes into this stuff. As has been pointed out. I use about 25 mods for Skyrim just dedicated to textures etc. Only 46 total. But I mean, they do it for free, granted they accept donations but still...
I have used creation kit to alter some weapons/armor (ring of carry instead of doing it through console) I'd love to learn more about modding it but it's really rather intimidating. I used to mod C&C RA: Yuri's revenge... but it was just....easier lol
