CrimsonEclipse
The One and Only
I really wished the Emperor quest was longer and more epic. In fact, Skyrim would have been way better if the combat was better. Only archery and unarmed are the only ones that felt the most epic to me, the rest felt like flailing around with a sharp stick.It is a close second. My money though goes to Dark Brotherhood, when do you get the chance to kill an emperor or act as an orc chef while being khajjit.
