For gameplay guide, installation order doesn't matter, but load order does, so read the mod pages/my own notes if preset carefully. For graphics mods installation, the order matters the most - so, for the best results, it's humbly recommended to follow the same order as mods are listed. This guide has both graphics and gameplay parts, two in one. Installation order, performance notes, patches list and personal recommendations included. List of 4500+ mods (but at the same time 'quality about quantity', including different variants to choose from) to install to make your Skyrim graphics look nextgen and gameplay feel on absolutely next level - everything structurized properly so you can build both mod setups, depending on your goal.
Skyrim has over 100 thousand of mods available and that's quite a task to check them all, but I spent some time and did this, and chosen almost everything you need to transform your game and also to have some variants of similar type of mods to choose from. My goal is a complete guide to save other people time that they can have a complete base list of mods for ultrarealistic graphics and challenging, nextgen gameplay, knowing how much these mods will affect on performance and in what order they should install the mods, which are compatible and which are not, etc. This guide is a brother of my Skyrim LE graphics and gameplay guides, in a single one - and a result of many months of modding Skyrim.
