the only people that repeat the same dialogue in real life are people that have a pathological disorder, in which case all the npcs in skyrim are crazy.

Um, doing things repeatedly and saying things repeatedly is far cry from the same thing. If I do something everyday, that's called "routine."

If I go up to some random stranger in a store and say "HEY! I work for Billy Bob at the General Goods store!" People will think I am insane (and) or punch me in the face. And probably after the third time of doing it, they would call the cops and drag me off in a straight jacket to the paddy wagon.

People like telemarketers are paid to annoy you, that is there job. It is not my job nor my desire to run up to people I don't know and say..."Have you been to the Ritz? Oh what am I saying, of course you haven't."

It's not the number of lines they have as much as how those lines are used. Is it really necessary for that kid to say the exact same line every single time they run past me? Seriously you think complaining about that is because I feel entitled. It doesn't mean that at all. I love this game and most if it is absolutely amazing. Unfortunately that makes certain things, like the often repeated dialogue, stick out like a sore thumb. I just don't get why they didn't limit it more, or give more people different things to say. You can travel across the entire game world to a remote town and hear exactly the same lines from a shop keeper spoken by a totally different actor. Why is that? Why couldn't they bother to give that voice actor different lines, break it up a bit. They get paid the same no matter what those 20 lines are so why not change them up. If it's about mundane things anyway it's not that hard to come up with a few unique quotes. It would make the game world feel so much more alive and the characters more unique. Instead they all say exactly the same thing over and over and over. If nothing else they shouldn't say the lines as often. It just drags the game down to have the same lines repeated so frequently.

exactly, i think they should have made the repeated lines into general conversational lines, for example, "what" "need something" "yes?" "can i help you?" "go on" and those kinds lines.

Because it's extremely annoying and unrealistic.

It doesn't bother me that much at all. I do like the suggestion of simple greetings like good morning though.

The guard who states he hates 2 handed weapons while using a battle-axe is just plain stupid though

Try this out.

Enter Bleak Falls Barrow.
Note the conversation between the two bandits.
Clear out Bleak Falls Barrow.
Return after 30 days (time to re-set the barrow).
Note the conversation between the two bandits.

These bandits are repeating the same lines on both occassions. On the latter occassion, they are supposed to be dead, and their boss is dead, and the claw has been returned to the Riverwood Trader. So why are they alive? So why are they talking about a man who is dead? So why are they talking about a situation hat has clearly changed?

This is beyond unrealistic. This is a mind-boggingly, immersion-breaking fubar situation.

Yeah, guards can say a lot of things but then ask yourself how relevant most of them are. I killed Ulfie and what do I hear afterwards? "They say Ulfie murdered the High King with his voice. Shouted him apart!". Right, because that's a meaningful thing to discuss when the rotten bastard is dead, right? Why not talk about the rumor that Ulfie pissed himself before the finishing blow?

Even worse, what happens when guards comment on your skills? Wait, how the heck do they even know your skills? How does that make sense? The implied thing here is that you're greeting them with "hello guard, I've got level x in skill y!!", which is of course just as ridiculously dumb as all that nonsense the NPCs are saying. Even so, a lot of the guard greetings make no sense. If you have high sneak then they call you a sneak thief, even though that just means you're stealthy but not necessarily a thief. A Force Recon marine can be stealthy but does that make him a thief? Well, according to BGS... And don't get me started on their "let's comment on enchant" nonsense, because my 30 enchant, 0 perks sword'n board / archer couldn't do anything significant to his rusty POS sword.

Meanwhile, all the non-guards have almost no dialogue options to speak of, and a fair few say utterly stupid things as greetings. You don't say "hello, I work at the grocery! I put things on the shelves!!" as the first thing to complete strange, at least not unless you're 10 years old or suffering from a mental issue. Generally, you don't actually say anything when complete strangers pass by because they are just that, strangers. If you had to say hello to every person you walk by, a simple walk in the park would make you deaf and any distance travelled on the sidewalk in a bigger town would be a visit in hell. If you had to say "Hi, my name is x and I work for Y at the Z" to everybody then a trip to the mall could take days.

No, a whole lot of BG NPCs didn't say much at all, but at least those who said something would actually say something that made at least a tiny bit of sense, at least when Minsc or Tiax wasn't involved. And their nonsense was generally hilarious. And you wouldn't be bombarded with utterly idiotic greetings from everybody. No, I far prefer BG dialogue over the Skyrim NPC crap-stream monologue.

And as for Witcher, I honestly don't remember any NPC spamming anything as useless as "I used to pwn, and then I took an arrow to the knee" or "Let me guess, super-strong monster slayer of legendary fame, someone stole your candy" or what have you. I never heard the same NPC continue to tell me that said NPC certainly wouldn't claim to be the best blacksmith, oh no, or that the NPC's spouse is busy kissing the local lord's ass.

By the way, I've even stumbled over an NPC who talked about how things wouldn't be right until Ulfie was sitting on the throne, but unfortunately that was well after I had finished the Legion quest line. That's either a wicked endorsemant of necromancy from a magic-hating Nord or a headbrick-worthy level of fail.

I don't mind the repetitive dialogue, I just hate that:
1. People repeat themselves SO frequently! You just told me that 6 seconds ago, I haven't forgotten yet!
2. People tell you their life story every time you pass them on the street. Why not just a "hello" or "good morning"...? I don't even know you, don't explain your hopes and dreams to me every time I sprint past you.

Some of it gets old; I like Mjoll as a follower but if i have to hear about the guy sh***ing his armor when she draws Grimsever again...I had Marcurio for a long time and I never got tired of his asides...Mjoll on the other hand...she needs to expand her breadth of stories..

"You're like me, eh? Don't fancy those clunky two-handed weapons" says the guard with the two-handed Warhammer on his back.
