First of all a big thank you to Bethesda for creating a great game. I've been playing since day one and having a blast, really awesome piece of work. The enviornments, music, quests, all well done. In the course of playing, I've seen some things I would love to see fleshed out more. So in the spirit of sharing ideas, I present mine, maybe some will find there way in the game sometime. Most everything listed here should be very doable with the mechanics already present in the game today.

Make silent roll directional (forward/right/left/back)

Vampirism
Expand on the idea, the "levels" of power are a nice touch, but let's remove everyone automatically knows your a vampire and replace it with your hunger for feeding increasingly grows dependant upon level to the point if you are around people you have an increasing chance of your character uncontrollably feeding on someone, thus alerting those around your a vampire. At level 4 you will most assuradly out yourself if you go into town. Perhaps a vampire faction, where you can find other quests and npcs to interact with.

Werewolves
Add the concept of levels, have the level grow dependant on the amount of time you transform and how often you feed when you transform, to the point at max level your powers are great, but you start to lose control of when you transform, bringing in the risk of outing yourself in town. Add the ability to temper/lower your level of feral by quaffing a craftable potion. Perhaps a werewolf faction, where you can find other quests and npcs to interact with.

six/Marriage
Surely we are at the point now where we can put these mechanics in the game, I'm astounded there are no courtesans, no brothels, really no racy/flirty options at all that I've seen. Don't care if it makes me a perv saying it, I think it would be a fun option to put in, and could be done tastefully, and frankly with the level of violence some of the finishers are really no excuse not to. A few suggestions:

• Get those courtesans and brothels in the game so we can get straight to business. Have it where you can actually work in the brothel if you want to make some coin.
  
• Put a perk in speech, call it seduction perhaps or add it to allure, this perk gives you flirty/intimate dialogue options with npcs with your speech level dependant on success. Could add another way to bribe/gather information.
  
• Have the possibility of contracting a disease if you lay with random folk often, curable with cure disease potion of course.
  
• Create a nice little animation (tasteful of course), centered around a bed roll/bed/tent as there are always some nearby where people are, similar to how chopping wood, mining and such are depicted.
  
• You could go so far as to add pregnancy, with the ability to craft a birth control potion
  
• Add a recipe for an aphrodisiac, with the ability to use the poison perk in the pick pocket tree to dose someone with it. Doing a stealthy mission and you don't want to kill a guard? "Poison" them with the afrodesiac and watch them saunter off to chase some tail.
  
• Have a status bonus after getting down (potentially offset if you contract a disease)
  
• After laying with someone, if you hang around you might hear some pillow talk that may lead to further quests, a local rumor, treasure/etc. Let that radiant engine go to work.
  
• More options in marriage, just not much there right now. Give a gift, dialogue options, and of course some intimacy.

Misc
Let us use the instruments you can find, already animations/sounds for male/female npcs using drums, flutes and lutes, and you can find them laying around but we cant use them. Have the ability tied to speech, let us learn songs in the bard college, let us earn coin performing at the local pubs. Let us overhear some dialogue that could lead to quests whilst in the pub, go radiant engine.
Fishing, instead of diving in a river and click festing for fish, let us use that fishing pole and boat you already have as an in game asset. Often I see a hunter at the edge of a river, with a fishing pole beside him he can't use.
Let us relax (as you would use a chair) in those hot springs and listen to gossip with the locals
Would like to see more "life" in followers. Comments, pointing out places of interests whilst traveling, generating some quests from them. Would like to see orders to give them made available within the tiered UI as well as in dialogue, like asking them to be defensive/aggressive, ranged, stay close etc.

Again, awesome game, thanks for making it, will be enjoying this for a long time to come.
