I've been wondering if there are things you're noticing that are different since 1.4 and 1.5.
-I've noticed burial urns are bigger
-Water has not improved but become murky
-when on the load screen with pictures, there are new pictures. I've noticed a steel helmet with black fur on top.
-I picked up a dagger today called Bloodthorne and have never seen it in 3 playthroughs.
-Forsworn armor looks different.
-Killcams are okay
- Urns do seem a bit bigger. owo
- That was part of the update. Water is more realistic, and it actually textures properly.
- Some new pictures are added when you finish certain quests and stuff, so there's that.
- Bloodthorn has been in since vanilla, I got it on all my characters and I've been playing since release. But I see where you're coming from, because there's a lot of things in Skyrim that I only just notice/realize after a few playthroughs.
After about 400 hours of play time I have never seen a dragon inside a walled city.
I didn't think that was something that was supposed to happen either, but I saw it on my current character when she was at maybe level 25 or so. That is the only dragon I've seen inside city walls in 700+ hours.
