I wonder if it would be possible/desirable to introduce an amount of randomness that would cause each installed gameworld to be slightly different. Perhaps using a unique source of entropy (Serial number, product key) variables could be altered in the game world that would affect non-essential elements (like where the best place to mine for gold is). It would be nice knowing my Skyrim was my own, and that all the answers couldn't be found by another's account of the game.

No thank you, I want the same product everyone else gets.

Sounds like a lot of work for something so little.
(disclaimer: I have no idea if that is a lot of work, not being in the industry myself - it just sounds like it would be)

You can already make Skyrim or any Beth game your own with mods, this seems like a waste of dev time that will piss people off.

Aye. One thing I love about Elder Scrolls and Fallout is being able to talk to my friends about stuff we have found and help each other out like "Hey, did you know there is a 100 gold in a tree stump by X place" Or "There is a really great ore deposit over by X"

So, no. I do not want this.

It would have to be developed that way from the get-go, and it's arguable whether the result would be better than a hand-placed game world.

Ditto here. That's one of the greatest things about TES. It's possibly the only game that provides you with stories to tell, as if you actually were on an adventure. My friend's funniest story was how he did the quest for Sanguine. Or at least I think it's Sanguine, I didn't try all the Daedric quests myself. It's the one were you need to liven up a party by removing everyone's clothes with a spell And Shivering Isles overflows with stories. I still like to tell friends about Vitharn
