I can go on and on about how terrible this book is, but what I am trying to say is, this book isn't worth the paper that it is printed on. If you truly need help in this game, you can e-mail me at Cfjoe068@msn.com and I will glady play online with you and answer any questions you have. I love teaching newbs what units do, and introducing the great world of SC to them the right way.
And I bet most of us are striving for SC perfecction, right? It's one of the most popular games of today, you know, if you don't play it, when you walk on the street people will point at you and say "hey look, there goes that guy that doesn't play SC, whatta case! When my son got all Fs in school, I said, "that's ok, you won the SC tourney and that's all that matters. Screw graduation ;)."."
Jokes and metaphor aside, I can assure you that if you really want to improve your SC skill, buy this book, it's well worth it and so much more... I know you probably play SC just for fun and not to be a progamer and travel to Korea etc. (neither do I), but it's more fun to squish others then get owned, you are happy instead of frustrated with just a little diligence and this game is a fine choice if you want to spend those endless-sleepless nights in front of the Computer ;).
While people who are tenatively picking up SC:BW for the first time will appreciate having a book to hold their hand until they acquire a feel for the game, any regular SC player will tell you that the book's suggestions border on laughable. I use this book for the maps, but thats it; its a nice bonues with the Battle Chest, but not worth buying on its own.
