It's been many years since I've played Oblivion, and I kind of want to get back into it. I remember spending hours upon hours configuring mods for Oblivion (back in 2006 and 2007), but I don't have that sort of time anymore. I just want a recommendation on a good, one-click overhaul mod that I can just install on top of my Steam copy, perhaps install a couple of clothing/armor mods on top of that, and leave it at that.

Any recommendations?

A couple of recent, or recently updated, ones:

Maskars Oblivion Overhaul: http://www.nexusmods.com/oblivion/mods/42780/?

Oscuros Oblivion Overhaul: http://www.nexusmods.com/oblivion/mods/44629/?

MOO & OOO works together.
