Hi

I am level 41, I have completed Dark Brotherhood questline, and now MQ (which kinda dissaponted me).
Any other things worth doing? Things that won't feel totally generic/prefab/randomly-generated.

Thanks

Go out and explore.

Go after the Dragon priest masks? Or do all the Deadric quests..... explore.

I create specific characters that usually only do 2 questlines. Keeps it fresh for me, but that's just my playstyle.

I think the MQ is better when the char is a low lvl, JMO, I've finished it 2 times, most of my characters at least start it for the dragons. ( not all though )

I've done all the questlines at least once except the DB.

TES strong point: open world. Explore, quest (lots of stuff out there to do), delve into dungeons.... Start in a section of the map you didn't fully expose. Pick any town, talk to EVERYONE. Pick up quests. Complete quests. Explore s'more....

Explore, you've completed a very small portion of the game.
