I was on the Skyrim GameFAQs forums two minutes ago and apparently there's this mod called Amorous Adventures. From what I can tell, it adds fully voiced dialogue and immersive quests to vanilla NPCs. One person on the GameFAQs forum said they couldn't imagine playing without it. Vanilla NPCs like Lydia suddenly begin to have a character and personality instead of being a packmule.

Is this true? Does it really add character depth that this game needs? Or is it some erotic content thrown out there just to act as mental Viagra (which is possible since the mod is from sixLab)?

You really shouldn't link there. FYI.

That being said, while I haven't used it, it has a decent reputation.

Keep in mind that unlike many other romance mods, this one is definitely X-rated.
