Wow, this is one thorough guide. The pull out map is a great addition. If you want to raise your skill points quickly you need to find as many of the skill books as possible and to do that you need this guide. It's great for finding those rare items too. In fact its good for finding anything. I like the way its set out you so you can play the game and glance at the guide for what you need. I needed it mainly for the exploration aspect, but it has full quest walkthroughs. And did I mention the bobbleheads? Part of fallout 3 is just wandering around and exploring, and this guide will complement that perfectly. A must buy.
