This guide is good, but I wish they had spent more time on providing actual strategy rather than making jokes. (Seriously, they try and make witty comments about every thing in the game, and they're just not funny. Trying to compete with South Park writing seems like a waste of time.) I'm surprised that the book was so heavy on screenshots and thin on useful text, especially when strategy guides as a genre are a dying breed (because, let's be honest, there is no information in this book that isn't available legally and for free on any number of gaming websites).
What I liked about the guide:
* Good charts, which give a semi-useful overview of the various items in the game
* The included map is indispensable
* Contains some good hints (e.g., always look for scenery to kill enemies before battles)
* Good as a reference, but not a guide
* Surprisingly uncensored
What is terrible about this guide:
* No "missables" section. Many of the achievements, characters, and artifacts in the game (notably the Chinpokomon, which affect several achievements) are miss-able: you get one shot to find them, and if you miss your chance, you can't go back. Most (but not all) of them are covered in the walkthrough, and there really needs to be a standalone section for miss-ables. For example, Lemmiwinks is in the game, and there's a tiny sentence in the book about this, but if you're not following the book to the letter, he's easy to miss. Similarly, they tell you how to complete all the side quests, but don't recommend when to do each of them--which is actually pretty important. The book makes it seem like you can do the side quests at any time, and you can, but I would have appreciated some strategy around when they SHOULD be done. (For example, completing the "summonables" quests, Jesus, Mr. Lee, and Mr. Slave, should be done first, so you can use the benefits of those quests in battle as soon as possible.)
* The Achievements section is really poor. They describe what the achievements *are*, but in some cases are WAY too general about how to get them (if they say anything at all). Their "strategy" for some achievements is "go get them!" For example, they don't list the location of the seventh (and hardest to find) homeless person, who is hiding near the South Park town sign. Some achievements (like, "Fart on 3 enemies at once outside of battle") are only listed, but that achievement (and others like it) really take some finesse and strategy to complete, and a description isn't really useful. A true strategy guide would list the best points at the game to get certain achievements, and techniques.
* It's missing any type of equipment or weapon strategy. The best guides will say "enter this area with the following equipped," or "this is the best combination of stuff." The book glosses over this, big time, and does the reader a disservice. They'll say things like "electricity is good here," when they should be saying "make sure you picked up this specific patch/strap-on, and use it here." For each section, they should have listed the best combination of gear, instead of "this is what you'll find in this area, [insert PG-13 pun here]."
Overall, this is worthwhile if you need a book to look up things occasionally--but if you're a completionist looking for actual strategy, be prepared to have the Internet handy.
P.S. This review is of the book only--it does come with an online code that has links to videos. I didn't use the online component, so maybe that's way better than the printed version.
