I myself am also curious about this. However I am looking to build a new rig to get rid of this old laptop and I've been looking into some mods myself, mainly large overhauls. I am going to go with STEP, GEMS, and Requiem for the 3 big overhauls then a bunch of individual/random mods such as CBBE w/ HDT, better vampires 7.0 or newer, some of the popular werewolf mods too, and other mods I can't think of right now. Also for this setup I'll probably be going with Dark Fantasy Overhaul paired with Bleak ENB, some fog, among other dark themed mods of whatever category. I can say STEP looks towards keeping things as close to vanilla as they can while improving the look of it. While GEMS does the same thing but game-play wise. Requiem is a large undertaking of game-play revisions much like old CRPG's such as Planescape: Torment, and the series of Baldurs gate & Icewind Dale. I know STEP has a detailed mod install guide, GEMS does not currently (at least officially), Requiem has a manual and a website to help with installation and incompatibilities. There are also a lot of mods with requiem patches. So I myself am looking to see if STEP, GEMS, and Requiem will be compatible with each other and if anyone has made a guide for all three. If I find anything I'll either edit my post or make a new one with my fruitful findings.
