I only go to novigrad atm to sell shyt.
I'm not touching quests there until I'm done with velen. Game is so deep I've barely talked to the baron. I'm simping keira right now
Novigrad is so big I have trouble finding the vendors.
And a ridiculous number of quests become available if you just walk around there.
I'm

at the devs not using any logic whatsoever in this game though. I had a quest open, level 6 I think, I'm level 8 so I'm floating through it.
The guy I was talking to said "meet me in this new area"....but the quest to get to the new area is level 15.
I said fukk it, I'll go there and just finish the level 6 quest. Lay low and come back to Novigrad....got killed on the way to the new place by level 15 enemies.
Fred.
