Don't know the name of this but it's the one that allows you to denock an arrow - check
Map Marker Overhaul - um, check

Anything else?

[not sure if this one should go into the mods section, it seems a bit off topic there]

There are hundreds of thousands of mods...so i don't know what could have influenced.

Well its obviously inspired by the monty python spells mod.

Natural Environments
Unique Landscapes
Animated Window Light System and Chimneys
Just to name a few.

Reneer's guard overhaul - Seperate bounties for the different holds

Yep. Bethesda were defintely inspired by user mods from Oblivion. Let`s see... Some of the names of the Mods I can`t remeber, but..

1. The ability to harvest and cook food came from an Oblivion mod.
2. The birds and butterflies defintely inspired from an Oblivion Mod.
3. Decapitations i am sure come from a bit of deadly reflex.
4. You can cancel firiing an arrow which must come fromthe `denock arrows` mod.
5. The just walking into a cave (instead of every cave having a door) might also be Mod inspired.
6. The window light system defintely inspired from as far away as the Morrowind mods.

There are several other inspired I`m sure but can`t off the top of my head remember.

That`s about it for now... I was half expecting to see an` eat food` Mod and `sleep` mod, but i guess Bethesda are afraid of alienating its console brethen.

The mods listed just gave the game more depth. I don't think Bethesda necessarily looked at them and said "Hey, we need to add this for the next game!" because a lot were just detail oriented that couldn't be put in Vanilla-Oblivion and still be handled by the hardware available in 2006.

But Obscuro's Oblivion Overhaul did catch the attention of Obsidian, who hired him for the production of New Vegas, if I'm not mistaken.

Can't believe no one's said this yet, but Reznod's Mannequins mod definitely influenced Bethesda. Aside from Harvest Flora and Denock Arrows this was the first thing I noticed. Also, companions and followers in general.

Yeah, forgot to mention that, that was actually one of the first thing I noticed as well when I bought the house in Riften. A nice addition indeed.

A shame we can't add DarnUI to the list..

Wow. You`re kidding! I even did some art for OOO, but lost touch after.

Midas Magic of Aurum. The "Storm Call" shout looks exactly like the "Lightning Storm" master destruction spell. The "Unrelenting Force" shout is also very similar to Force Push/Force Ball. "Fire Storm" behaves exactly like "Fire Burst" in the mod. "Ice Form" behaves almost exactly like the "Freezing Ray" spell. I could go on and on, but it's pretty apparent that Midas heavily influenced the magic system in Skyrim. But unlike the magic system in Skyrim, the mod spells actually scaled.

The 'lamer quests' mod

The weapon plaques, bookcases and mannequins are mod inspired, im sure
