i'm sure this gets asked quite a bit...

[the_grip]

i've finished the dark brotherhood, the mage guild, the fighters guild, the arena, the thieves guild, and the main quest. Are there any fun plots that i can jump into at this point, or is it all mini-subquests that i have to learn about from the right folks?

[Phatose]

Sounds like you hit all the majors, so yeah, you're down to the minors.

[LancerChronics]

yah, that's all the majors, though if you want to add to your faction resume, you can become a Knight-Errant of Leyawin, you can also join that vampire hunter's group in the imperial city. There just one or two quests each, but it adds more items on your list of guilds.

I finished the Dark Brotherhood and Mage's Guild quests and just now finished the Main Quest. I'm bored.
