I'm playing through Enderal SE right now with the Enderal VR patch. It's a really nifty total conversion with tight Gothic-esque world design and its own mechanics. I'm playing a phasmalist right now and can harvest souls to turn them into companions among other things. I use a lot of graphic overhauls and replacers for it to give it an entirely unique set of creatures rather than just reusing the Skyrim ones as well. I use a few addons like Myths and Legends VI and Riversville Catacombs for extra content. 

Also, extra player homes. I haven't bought it in game yet but I'm planning to get the Wellwatch Manor to stash my stuff in.
