So while it's neat that I have Summer in Skyrim, and it's fun that I have wooly rhinos roaming the meadows of Whiterun and a drunken Dovah-Bear load screen, it's SKSE that makes a real game-changer like SkyUI possible. exe that makes a lot of the more advanced mods possible through what I assume is black magic. Stuff like Skyrim Script Extender (SKSE), which isn't really a mod but a. Something I didn't really appreciate until I started to play on the PC and mod myself was that the 'best' mods were the ones that either laid the ground work for more complicated scripts and mods that wouldn't be possible without the vanilla game, or fixed some fundamental flaw or shortcoming with the vanilla game.
