Sacred Haven of Debauchery

I mainly download large mods for new quests and locations, and I look for mods with a lot of cool content. There aren't many mods I can wholeheartedly recommend; some are just plain boring, but there are several excellent, good, and simply enjoyable mods that have given me many extra hours of enjoyment with my champion, which is essentially why I download them. Plus, I tend to avoid some mods because I don't like the description or they're just not my thing, like horror mods.
And yes, I also downloaded mods for Oblivion, but I've kind of lost interest in it; there isn't much good stuff coming out, and besides, Skyrim is better and less demanding.
