Those that explore it all will find five cool side quests and a handful more unmarked quests that can easily eat up hours of your time. The same care and attention to detail was put into this area that you find in the Capital Wasteland which makes this densely packed area one of the most rewarding places to check out in all of Fallout 3. There's a lot to see here, as well. I spent an entire day wandering the swamps and still haven't seen it all. The quests will take you about five hours to work through but you can easily spend a few more just seeing the sights and working through the unmarked quests. Bringing the lighthouse back to life was my favorite little extra."
