Does anyone know why all npc say the same thing? Was it a programing issue? Was it a money issue?

I mean they could have hired anyone to act the few pieces of dialogue that the npc's say and everyone would have different voices.

There's more unique voices than compared to any previous game. There's also more npcs than in previous games.

Not a programming issue, because it applies to virtually every NPC in the game it can be concluded that such was intended, no it was not really different in past games, the problem is NPC's are literally TES versions of Fallout NPC's they have nothing to say past the first line if they aren't related to quests.

it also has to do with the distribution of voice actors, 70 VA's and apparently you only hear 10 of them with the remaining 60 having about a paragraph worth of dialog.

Can somebody please post the video of that game where they actually did that?
Doing proper voice acting is nothing anybody could do!

Sounds like it, also you hear the same stupid comments all the time. Everybody hates the female blacksmith in Whiterun as you spend so much time crafting together with her and she goes on about his father. Cutting timber at the sawmill in Riverwood and you started hating Lud, the mill owner who goes on and on.

The special actors are probably reserved for quest characters you only meet once.

Chaos Wars? Crap, man, don't even get me started on that

People always say things like "Come on, man! Ain't like everyday dialogue is hard!" well there is a reason "voice acting" is a job. Just like dish washer: it may look easy, but when you hear the destruction it wrought upon your ears, it's too late.
