Fans of Fallout 3 already know that the game's list of downloadable content is a mixed bag in terms of quality. Some expansions amounted to little more than drawn-out shooting galleries while the controversial Broken Steel add-on locked the game's true ending behind a paywall. On the other hand, Fallout 3's best expansions ventured into unexplored parts of the post-apocalyptic wasteland, often leading to creative stories that couldn't exist in any other setting. No other expansion demonstrates this better than Point Lookout.
