Additional Content Brings Greater Closure to Excellent Game
The game play matches with what you may already be familiar with in Fallout 3. There weren't nearly as many glitches, but the visual inconsistences have no end in sight. There was a section of the final battle where the ground I was walking across kept cutting in and out. The texture wouldn't sit still. It started to make me feel a little sick.
The voice acting was spot on and if you sided with the Brotherhood, the reaction from them for your victory and sacrifice was genuine. The difficulty of the add-on was not great. I grant you, I was at level 28 to level 29 while playing it, so the game feels much easier when you can go into the VATS system and get a bunch of shots off. The levelling in the game made the last few levels so easy.
Overall, I understand why this add-on was made, and the ending had a much more lasting effect with this added content. At the same time, I felt, like the rest of the add-ons, that it felt like an add-on. There was no seamless integration despite being placed right within the Wasteland, unlike the rest of the DLC. I would recommend playing this with the main game, but I would lower those expectations after playing a stellar game.
