Yep, that's what I had in mind. Randomize world generation, then leave the world static until the game ends and a new world is generated. Increases replay potential IMHO for RPG's and such.

I'd like to do that for my current space project, place planets, starbases and other interesting items at random locations, generate a new start location for your favorite baddies, and off you go to explore "where no man has gone before"...

Cheers!
