It seems that a few things have been revealed about the Elder Scroll V: Skyrim. Infinite quests and larger expansive DLC’s are two things discussed during several interviews with Todd Howard and Wired.com. It was explained that even after finishing the game; you could still play on doing quests that are randomly generated based on your progress.
Larger DLC – There will more expansive DLC, but there will not be as many as in previous titles like fallout 3 and Fallout: New Vegas. They are going to focus more on quantity rather than releasing some small quick selling DLC’s.
Infinite Quests – Tom Howard talks about the Radiant Quest system. This system will allow you to continually have quests available without ever running out. The entire system is based on how your progress is in the game. From being sent to locations you haven’t visited or sent to assassinate unsuspecting victim, the quests will always be something you can do before and after the endgame.
