Well I've found bodies of people I've killed ages ago.

But the dragon skeletons appear to have disappeared. Most notably the first one you kill during the main quest has disappeared. Odd.
Suppose they could hand wave it as being other dragons coming by and reviving them again, but not if others have perma-skeletons and I don't...

Supposedly infinite, and I can confirm that dragons do respawn. I fast travelled to one of the places where a dragon resides, and suddenly found myself assaulted by the resident angry reptilian monster, even though I already killed the one on that place twice. :U (so now it's triple dead)

They are certainly infinite, but with a higher respawn rate before you finish the main quest and a lesser one after.

I am interested in testing out the theory that there are infinite quests due to a quest generating system or something like that. SO far it did surprise me in some parts, especially one time when out of nowhere two children appeared and stopped playing so one of them could sell me a map to a treasure or something like that.

As far as infinite quests go, "The Dark Brotherhood Forever" is essentially one.
I think.

Possibly the "find the hidden treasure" ones too.

4zb41, the skeletons may not have disappeared, i have encountered strange bugs where the dragons skeletons start rolling or flipping away, sometimes bouncing into the air, it's happened to my friend as well haha. I must admit it looks quite hilarious .

Usually, that is the case, though. Most skeletons will dissapear, not flip away, even though I came across that glitch with the first ever dragon I faced. :P

Also thanks, shook. I want to play so badly right now, but I still haven't gotten my damn xbox back yet, or supposedly a new xbox that they said they would send me.

Hopefully I will have it within a week or two. If not, I am probably going to borrow a friend's xbox or something lol.

guess waht guys! just finished main story. didnt get anything from it tho D:

Anyone here playing on Ps3 notice the dreadful lag? Hopefully it is fixed soon.

Agreed, all I do is hunt elk.

I've been using sneak and sky-forge steel daggers for epic throat-slitting kill scenes. If you didn't know, there's a perk to get 15x sneak crits with a dagger for sneak.

Also, I haven't come across any glitches so far and I've played through the main story line once. Maybe it's just the PC version or plain luck.
