And I love it, but:

-Nobody seems to have an opinion about things that should be important to them. Your friend died? Ignore him and keep walking. Your town got captured by the rebels/imperials? Meh.

-Towns seem unlively. People don't travel, or talk to each other alot. Taverns always have the same people doing the same things, with nothing there except maybe some quests and a bed for your character.

-Melee is still spamming left mouse button, and power attacks.

-There's too few skill perks, and not enough variety in them.

So far, these are the only flaws in the game that I've found. I lament the fact that Bethesda didn't spend much time on the player's experience with other npc's.
But I aplaud them for making one of the most immersive games I've played yet. (If I'm not questing or spend too much time in town's. Or pretend that Lydia is a person and not a robot )

What is your opinion?

are you actually familiar with pubs ?

I know, I know. They look like inn's to me, but the npc's only seem to be there to play animations and lines of dialogue, and nothing else. It's just a place you run trough to get to your bed and back out.

Aren't inns places for travelers to sleep? There's supposed to be interresting tales and people to meet in inn's. Now I just enter and exit them without thinking.

some things the NPCs do don't make any sense. for example, if a guard notices a prison door hanging wide open, and you sneaking about nearby, he doesn't put 2 and 2 together and arrest you.
if you walk past 4 or 5 NPCs in a row, they start talking all at once, as though they don't realize someone else is already talking.
and you're the only person in skyrim who doesn't actually "eat" when he eats.. there's no eating animation. same with sleeping.
the oddest thing is how so many male NPCs sound like Farkas.

Well.

one night in a pub, I slept with the Jarl of Winterhold watching over me, guarding my bedside!

That was pretty cool.

Ever been in Denmark during winter time..?
