Previously I've been pretty gentle with modding that game - things like SkyUI to make it a bit more PC friendly, utility mods like the one limits soul gems to ONLY being filled with their highest tier (no more wasting a grand by filling it with a mudcrab). Also LockPick Pro to effectively skip lockpicking, cuz I hate Skyrim's (bring back Oblivion's model!)... that's kinda it.

Looking for mods that bring something new to the actual gameplay. I know there are a ton of them - what are your favorites?
