Summary: The idea of going to the South seemed kind of boring for a Fallout 3 location. But I was greatly surprised at how immediately fun it gets right off the bat. It doesn't have the same crazy difficult decisions as in The Pitt but it does have some hard ones to make. The DLC doesn't offer much with weapons, the only two I found were a microwave emitter and a more powerful shotgun.
Summary: My son and I play the base game, Fallout 3, all of the time. He has gone onto complete the game 3 times. We got this, and he took off. It adds itself into the main game perfectly and flawlessly. The overall play is just the same as the game, but a whole new area. The fights are a bit more difficult, but that just adds to the gameplay challenge. If you have Fallout3, get this!
Summary: I purchased this as an online download. I played it with a level 20-30 character(after installing the Broken Steel download that raises the level cap), and earned about 4 levels while playing it through. I think this would still be an excellent experience even playing with a level-maxed character, because of the tight quests and very effectively staged battles.
