I'm getting Skyrim tomorrow. Are there any must-have mods that you should install before you even boot the game up for the first time? I'd like to experience bethesda's game for a while before I install some of the more radical mods but, for instance, the UI mod I looked at seemed to be one that you just SHOULD install, regardless of whether you want to experience vanilla skyrim (as I kind of do, for a while at least). Are there any other recommendations?
Also, is there a kind of mod guide around. I remember there being a good one for Oblivion.
