I apologise if any of these questions have been answered before, or if I'm posting this in the wrong place. I bought Skyrim last week, but I still haven't played it, as I'm hoping to have everything set up before I jump in. I keep seeing "STEP:CORE" and "STEP:EXTENDED", and notes for those using either build, but it's not clear exactly what "STEP:EXTENDED" is. There are many times throughout the guide we are given detailed instructions, but it is difficult to discern requirements from recommendations, as they always begin with "STEP Recommends:". We are told to install certain optional files, or to install older, lower res versions, but reasons behind this are rarely addressed - "Serious hd retexture Skyrim LANDSCAPE 2K 3.0 beta" and "SHD FULL - Landscape" seem a lot more enticing than the "1024p" and "lite" versions. I'm half way through the step guide, but before I go any further, I'd like to know what my options are - what mods will conflict, and may I substitute any of them (especially concerning the "landscape and environment" section). By the end of this, I'm hoping to jump in and play for a few hours with most of the texture and graphic overhauls disabled, then enable them all to better experience the "HOLY CRAP amazeballs!" feeling often evoked by /r/SkyrimPorn/. I have quite a beefy rig, so I'd like to max out everything, simply because I can - so I would appreciate any recommendations.
