PS: Not finding a suggestions forum. I probably overlooked it, sorry...

Skyrim has it, it is called Radiant Story if you didn't know

Heh, I don't think that is what the OP is talking about at all. Radiant Story is a random side-quest generator, near as I can tell.

There have been a handful of times where I would reload a save after death or if I accidentally did something, and the exact same play through had different enemies and items and different quest NPC's. That is Radiant Story at work.

Remember when you could use a program like RPG Maker to re-create a game like Zelda for NES in a matter of hours? Good luck doing that with Skyrim.
