Because I used to read PlayStation Magazines, I ended up with various Walkthroughs, that I read in my spare time, some of them are really well written as I've said before, but some of them have moments that look like they didn't do the research on the game they were guiding us through.
For one guide for Final Fantasy VII (I have lost this book, and want it back - it was a Tips and Tricks style book, it mostly had cheats, but a couple of games had walkthroughs) that got a couple of boss names wrong (I guess they didn't know about the help window?) at the end (just before they talk about the North Crater) they give a rundown of all the things in the game left to do, and simply say that there are some caves and a platau (the Anicent Forrest, I guess.) that are inaccessable, but doesn't say anything about how you get to them. There were probably other things as well, but I still want to read it again, because I liked the style.
One Play Magazine free walkthrough for Resident Evil (the main book was for all possible outcomes of each scenario on Resident Evil 2, which changes depending on who's mission you play first, or something.) The section on RE1, the walkthrough stated that there are two giant snakes in the game, when it's just the same one appearing twice (if it wasn't made obvious by the fact that in the first encounter the snake doesn't die, Capcom have confirmed this fact). Also, the same guide states that one of the STARS members suicides himself, when he doesn't (although to be fair on them, the way that scenes played kind of makes it look like he does).
Do you have have any?
