Visit a tavern at night. There's a barkeeper, 2 or 3 visitors, no life at all. In one tavern there are even background noises of crods speaking, but I watched everywhere: the crowds are not there. Only a few people.
College of Winterhold. It looks huge from outside. Inside you'll see a few staff members and about 5 Students.
I mean Skyrim is great and I love it, but way too few npc's and interaction amongst npc's.


but if someone would like an idea for a mod (which i could never use for my xbox, but would gladly toss the idea out there) make a composition system similier to that of the online mmorpg "mabinogi" it is pretty awsome when you get to learnign how to make music on it (i can only make lillium though
)
