Weren't the original elder scrolls games mostly random generated? I'm pretty sure Daggerfall was almost completly RNG.
Daggerfall's quest system is very similar to the Radiant Quests in Skyrim. However, I feel Skyrim doesn't quite have the same spirit behind them. I think it's because there's so few of them. Daggerfall had over 200 quests with random target objects/locations, and there was less restrictions on who could give which quests. They also had nice mini-stories on them. Someone is being threatened by %enemy% who were coming that night and you had to hang around and protect them... you randomly get accused of stealing something you didn't and were lead on a merry chase around the region to clear your name (all the while you were pursued by guards)... someone was on the lamb and you needed to escort them someplace while ducking the guards... and plenty more like this.
In Skyrim on the other-hand, there's relatively few quests that work like this. And of those few, they're restricted to specific quest givers. There's not much variation with the radiant quests Aela gives, for example, and there's very little story to them. There's almost no involvement with the quest giver themself, from what I've seen, and its as basic as a kill/fetch quest can be. A beast invaded someone's home, go kill it*... the Jarl's men came by and left this letter, go kill the bandits/dragon/giant... there's a dispute, we don't care about the details, just go beat someone up... there's very little reason given for a character to care about any of this.
Not that the system itself in Skyrim is bad, but there's strong disparity between these few, ultra-generic radiant quests and the various "pre-written" quest lines, which makes them stand out as drab. I'd actually be interested in seeing a number of http://uesp.net/wiki/Daggerfall:Quests redone in Skyrim's Radiant Quest system (particularly the vampire quests and merchant/innkeeper quests, as they're sorely lacking in Skyrim). There is great potential, but un-modded Skyrim really doesn't take advantage of it.
* Funny enough, there was a quest similar to this in Daggerfall. But it was given with much less frequency, and it's not exactly a shining example of Daggerfall's quests.
