For a while I have been trying to recreate some of the base effects found in Requiem but finding that I fall just too short so I am coming back to Requiem and I have decided to start from scratch with the things that are really important.
In my experience for role playing I have found that the essentials simply could not be ignored. http://www.nexusmods.com/skyrim/mods/11163/?, http://www.nexusmods.com/skyrim/mods/33201/?, http://www.nexusmods.com/skyrim/mods/26228/?, these three made up the essentials in my mind. Unfortunately Frostfall just doesnt seem to work. Its made well, no doubt about that, but with its resource demands getting it to function in anything but a first class rig is pretty much impossible. Fortunately it seems, http://www.nexusmods.com/skyrim/mods/6745/?tab=3&selected_game=110&navtag=http%3A%2F%2Fwww.nexusmods.com%2Fskyrim%2Fajax%2Fmodimages%2F%3Fid%3D6745%26user%3D1%26gid%3D110&pUp=1 looks to be the worthy successor. These guys together put demands on the player for rest and nourishment, keeping warm in the cold wilderness of skyrim and the general notion that you need to be prepared for challenges that you would find both in and outside of combat. http://www.nexusmods.com/skyrim/mods/44623/? adds time as a real factor in the decisions that you make, which pairs very well with the above mods.
Next on my list is NPC and animal content. Wild animals just arent any fun unless they behave realistically. http://www.nexusmods.com/skyrim/mods/10175/? seems to be the only mod that I know of that will work well for fixing whats wrong with animals.
NPCs are more complicated, and by far more interesting. http://www.nexusmods.com/skyrim/mods/12977/?, http://www.nexusmods.com/skyrim/mods/31264/?, and all the 'Populated' mods, http://erkeilmods.altervista.org/skyrim/populated-lands-roads-paths-rs/ for example, make things really interesting. Get the right carefully chosen NPC mods together and it makes for a wild experience. With these I find situations were stormcloaks and imperial soldiers are fighting in groups of dozens on the road. A wide spectrum of travelers from other adventurers to traveling merchants being found on the roads. After seeing with these mods can do, not having them would make the world seem dead and empty. Plus, a great benefit i have found, if you find yourself against an enemy that you just can meet no matter what you do. Get that enemy out on the open road and your bound to find a whole team of people willing to help you out. xD Still trying to find something for behavior though, no matter what NPCs still act like robots, not sure if there is anything that can be done about that.... Something else ive noticed is that mercs dont seem to be hirable anymore... Populated lands roads paths has a feature that allows you to hire mercs but I cant get it to work anymore, odd...
http://www.nexusmods.com/skyrim/mods/50740/? and http://www.nexusmods.com/skyrim/mods/49496/? are great mods for managing all the loot in the game so getting lots of money and high level stuff isnt so trivial anymore.
All of that being said, im trying to think of other mods that I would characterize as essential. Nothing else is coming to mind but this list is far from over. i still want to look at economics mods and stuff like that to make money more meaningful rather than just having it pile up after you have all the weapons and armor you want.
I also want to have a section on here to make sense of all the patches for everything. With stuff like this there is bound to be a ton of patches and making sense of all this would be ideal.
