What 'social' aspect of the game would you improve and how?
If you are not sure what I mean by 'social' aspect of the game, I'll tell you..

• Marriage, and life after that.
  
• Interacting with NPCs that isn't quest related.
  
• Having kids, setting up a home.
  
• Growing a garden.
  
• etc..

So my question is what do you feel is missing for your 'social' role playing life in Skyrim?
And what could had been improved and why and how?

Barring NPC true AI, I think NPCs that actually approach you to open up dialogue is something that is seriously lacking in most RPGs. The premise, I guess, is that the PC is hunting down quests, not the other way around. But, once the PC gains a little fame, it would stand to reason that people in the are would want to speak to him/her beyond the "hi, how you doin'" pleasantries. Sometimes this might lead to quests, other times not. You get a hint of this as NPCs talk to you while you're passing them by, but wouldn't/shouldn't they position themselves face-to-face at least sometimes? For example, Brynjolf does EXACTLY this. But, IIRC, he's the only one beside couriers. You would think maybe some really insistent beggars, at least, would make such nuisances of themselves that you'd flip them a coin or bottle just to get them to leave you alone. Other than that, marriage... meh... kids... meh... gardening? huh? What's social about gardening?

Add back in disposition. Removing it was a horrible idea.

I have seen a lot of NPC just pop up in front of me or just move from A to B without walking to B, just vanish and pop up some other place in some of the towns.
That feels a bit weird as I used to believe they had a 24\7 daily life, as in Oblivion -I think- you could stalk a NPC for the whole day and they wouldn't do vanish and pop up somewhere else.

Also when you go to sleep in a tavern after the barkeeper had followed you to your room and you go to bed for 8 hours and wake up, everything is the same. The barkeeper is still next to your bed as you slept when she was next to the bed after 8 hours and the music\noise will continue right after like if no time has passed.

I think it would be a blast if game let you actually rise your adopted child. You would be able to teach your child various skills, train in combat, take for small adventures suited for current age and skills, and just watch how your child grows and becomes adventurer

As an ersatz, I modded our Khajiit child Ma'isha to be able to follow us and fight. It was amazing experience to take her on her very own small adventure to fight aggressive skeevers.

I posted that pic already, but here it is again, just to let you imagine yourself taking your game kids on adventures

the NPCs are shallow in skyrim. in skyrim most npcs only live for the character (some never even sleep), in oblivion every npc had a life they went through. skyrim's characters never talk to each other (save one scripted conversation that repeats over and over and over and over and over and you get the point), oblivion's random conversations may have put most of them in the loony ben in real life but at least they said something. better thought out and well written characters in general would also have been nice.

The minigame connected to it in oblivion was an equally horrible idea.
Add it back in but connected it to dialogue choices for petes sake,
make choices acctually have some weight.

sleeping only affects time, look at a dragon from a distance and wait as long as u want it will still be flyin around

I'd like to be able to give NPCs gifts. No more reverse pick pocketing.

seconding this. i want to teach my kid how to 360 noscope some deer.

wall of text time

i don't care about deep dialogue trees or hearing about somebody's life story, because that life story always winds up making me go out and get some [censored] old weapon from a cave i had no desire of going to. i just want people to DO STUFF. nobody stops and chats about the weather, or rumors, or anything. the problem with that in Oblivion wasn't that it was THERE, it was that there were 10 voice actors and you heard the same [censored] constantly. it was a GREAT little idea and one that i'd really hoped would stick around.

like, the fact that they go about doing jobs and [censored] is a MASSIVE step up over Oblivion but at the same time that's pretty much ALL THEY DO, and they do it regardless of any external circumstances. nobody reacts to the weather or anything, they'll go on chopping wood even when it's raining so hard you can barely see ten feet in front of you. then you have people like innkeepers who literally stand there 24/7 and never sleep or anything, which i can understand to an extent, but if inns locked up at like 3AM or something that would be a great little touch.

i also want people to move around the world more. remember the guard near the Imperial City stables who would occasionally pop down to Weye for a drink at the inn? or the way the countess of Leyawiin would visit her mom every couple of weeks? that [censored] was great, and is pretty much nonexistent in this game.

i recently saw Talsgar the Wanderer performing in the inn in Whiterun and thought he was going around the world on his own actually visiting different inns and performing in them but apparently it's just a random encounter. i don't want random encounters replacing the capabilities of Radiant AI. there is a lot that Bethesda can and SHOULD still do with the system. apart from ALife in STALKER and the Artificial Life stuff in Egosoft's X games, Bethesda is the only developer who actually puts any amount of effort into making unique individual people live out unique individual lives.

i get that a lot of it is console memory constraints right now and that next gen will be better, but i really don't want them to get too used to just doing with random encounters what they should be leaving to the AI. there isn't nearly as much focus on emergence in these games as there should be.

Well, I'd improve marriage life, by having six minigames with your spouse. It would require the "nvde bodies" mod, but if you could get that mod, you could invite your spouse to bed and, with the right button taps and joystick movements, timed just right, you can lay down your moves and make your spouse squeal like a pig!

If you're a man, and your spouse is a female, your wife could also get pregnant after a successful completion of this minigame. She will be disabled as a follower for nine in-game months, and when that period is over, a child of her race will start living in your house for no apparent reason.

Marriage - better dialogue once you're married. This could include random comments from your spouse about how their day was (when they're not following you, it would be weird if they mentioned how they went shopping when you know they've been dungeon delving with you all day), giving them gifts (including clothes, weapons, jewelry and armor they would equip), and some dialogue options that actually show affection ("I missed you when I was away", "I love you", "I'm so glad I met you" or things like that).

Having access to followers' and spouses' full inventory without mods.

Shorten the generic greetings from various npcs. It's fine if people you meet on the street say "Hello" or "How do you do?", but why Sigurd has to tell you he works for Belethor every single time you pass him by is beyond me. And we don't want to hear Nazeem go on about the Cloud District any more. At least, give us the option to say "Yes, in fact I do - Thane, you know" or something.

The ability to turn down quests. When Brynjolf jumps you in Riften, you can tell him you're not interested, but the quest still will be in your journal. It's just one example, the game is full of this. Just let us say "no", and if we change out mind, let us find the questgiver again and start the dialogue ourselves instead!

Also, agreed about better or more complex schedules. Bards and innkeepers actually eating and getting some sleep. Jarls doing anything but sitting on their throne and go to sleep in the night. I've seen Balgruuf and Laila sit by their tables sometimes, and Ulfric moves around a little before you start the CW questline, but that's about it. I would for instance be great if Ulfric in fact did visit the Temple of Talos, as the priestess claims he does, and if all the Jarls had regular meals and maybe some martial exercise (they DO look way too fit for someone who sits all day). Not move around too much, since they are questgivers and could be a little hard to find, but we have the floating marker for that, don't we? And other questgivers do in fact move around - for instance the Companions, I've been reporting quests to Vilkas in the Falkreath forests. Which brings me to the next thing, other factions than the Companions should work. Let us see Vex sneak out of a house in the middle of the night. Let us meet other TG or DB members on their way home from a job. Let someone from the Bard's College actually perform in the Blue Palace occasionally.

Occasionally the wife will give you gifts, usually a piece of armor or something. The problem is that it's often way lower spec than you're wearing and all it's good for is selling for a bit of cash.
Ysolda (bless her) once gave me a leather vest when I was walking around most of the time in the Nightingale armor.
I would love it if they actually did equip the stuff you gave them and kept it on. I have tried to make them equip something but I went out and came back and they were in the same stuff they had on before I had them equip what I gave them. This would actually be good if you could have characters like Ysolda do it as well if you're married and not just followers. I'd love to see Ysolda in a nice dress since she doesn't go hunting with me and there are some mods with some nice clothes and heels too that would suit her. Have your wife look like a real lady instead of a poor scullery maid.

Nazeem and his cloud district comment gets annoying. I swear if he says it one more time, I'll send him to another cloud district myself where he can while away the hours annoying someone else with his harp. There are other NPC's that have the same line over and over too. Taarie is also one of the annoying ones, always making rude comments about your attire, I wish you could have the option to shut her up by making a similarly rude comment about the rags she sells, maybe telling her that they are good for dishcloths and not much else.

I'd like real consequences to my actions. For instance, if you murder someone in a town, and then pay your bounty, everyone acts like nothing happened even if you murdered the person in broad day light infont of them. After something like that they should be reluctant to speak to me. Everything feels far too static. And I'd like to echo others thoughts on sleeping/activity schedules for NPC's. It would be nice if they were more refined.

I'd like NPC's to acknowledge my current status. When I'm the leader of a guild, I shouldn't get suggestions to join the guild, or that I'm still the newbie.
