I was hoping you people could help me spice up the main quest a little with some mods. I've already started the main quest, but haven't dug far. The only thing that alters the main quest that I added are TIE and Cloud Ruler Temple Alive.
I have my eyes set on Enhanced Daedric Invasion, but I'll have to think a little more about it since TIE makes it very difficult and the fps drops pretty quickly already as it is if a bigger fight breaks out.
They don't have to be anything specific, anything that helped you spice it up even if it wasn't directly "altering" the main quest.
I just remembered how awesome the main quest is after starting it again, after a while. Baurus is also one of the characters that I value a lot in Oblivion, despite the game being what it is, they did a good job with Baurus. His character is really admirable. The member of the Blades and Martin haven't shown any behaviour that could tie them to the "evil" history that the Empire has written over the ages.

Thank you for all the replies.
