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.
