1. and 6. sound really nice.

Though big problem for 1. is that rather important people could get killed more easily. Especially when a dragon attacks.

Haven't tested it but I like the idea of this one:
World Map in full 3D

I wish there were mods that would change the game to be more like Oblivion. I think there's a few in the works but not many released so far.

50% Faster Cell Respawn: repopulates the world and dungeons faster

Dynamic Merchants: Makes it so more you trade with a merchant more money they have, later stock levels and item availability will be tied in

Shadow Striping Fix: fixes the shadow striping caused by lights such as the Breezehome fire pit, not blocky ness tho unfortunately

RWT Realistic Water Textures: Higher resolution water and more "realistic" water

I'm starting to look for some more gameplay mods now that I have played a lot of vinila, I also have a few smaller tweaks and fixes but they aren't worth posting IMO, I'm also using House Map Markers lol

38 of them. I had to pry myself away from the Workshop so I could actually try the game out!

Some of my favourites:

Alternate Start is a godsend. It allows you to skip the whole tedious Helgen sequence with the long conversations and death row and confusing hiking through ruins, and start pretty much wherever you like. I chose to start as a soldier in the Stormcloak's army, and I spawned in Windhelm. It's easy enough to do the main quest: you just go to Helgen, kill one guy, pick up a diary and head to Whiterun to continue.

Legible Road Signs is self-explanatory but it's great not to have to check your map constantly.

And a fun one: Divine Punishment for mention of arrows in the knee simply causes any guard who says that awful line to be struck by lightning and killed.

Tagged so i can watch those videos later.

The trouble with Open Cities is that you need a supercomputer to run it at more than 10fps. It's really not worth it for the benefit of getting rid of a few loading times.

I was having this too, but I uninstalled the Texture Pack (one of the first mods I got, a Nexus one) and that somehow fixed it.
