I found out a few days ago that Bethesda will be releasing some expansion material for Fallout 3. They’re calling it downloadable content (DLC) and it will be available through XBox / Windows Live and directly from Bethesda. The first DLC will be called Operation Anchorage and will be a prequel involving a battle during the war with China. It will be released on January 27th for $10. There will be a total of 3 DLC expansions with the final one expanding the main quest from Fallout 3 and raising the level cap to 30.
I’m still playing Fallout 3 and it’s still a lot of fun. The game is huge, but throws so much at you that it is not boring. If you start getting bored, you can change direction (for example, I had been exploring the wasteland not doing any quests, and I decided to go back and advance the main quest and a side quest).
I picked up the Collector’s Edition game guide a couple of days ago. It is a nice hardback guide with everything you would want to know about the game. It includes a fold-out map of the wasteland with major and minor locations noted and cross-referenced in the book. The only difference between it and the regular game guide (besides the $10 price difference and the regular guide is soft cover) is I think it includes some material about the development of the game like the Collector’s Edition of the game does. Check out one or the other if you want to know every nook and cranny of the wasteland.
