Review: This book outlines hundreds of different routes up all of the Wind's well-known peaks (as well as several not-so-well-know ones). He did a phenomenal job amassing all of this information. There is enough here for a short lifetime of awesome mountain trekking.The information Kelsey gives is mean, lean, and straight to the point. Novices beware, this book makes no attempts to come down to anyone's level. It is written for those grounded in that arts of route-finding, technical climbing, and alpine survival. It is not a hiking book. If you are uncomfortable with this, either buy a more toned-down Wind River guide, or pick up a book to build your skills like "Mountaineering: The Freedom of the Hills" and start psyching yourself up for some world class backcountry. 
 Polarity: Negative
answer:
False

Review: I agree, the CDs are a much needed help, since it would be impossible to pronnounce the Yoruba tones without the help of a native speaker. However, the design of the book is really poor and confusing. I have found several spealling mistakes in English and Yoruba. And the grammar explanations are very hard to understand.Unfortunately there are not many Teach Yourself Yoruba books that are worth it. This one at least provides basic vocabulary and pronounciation skills. 
 Polarity: Positive
answer:
False

Review: Outrun was the biggest disappointment of my holidays.If you've just come home from a life in 1985 you might enjoy this. I read the reviews before buying but it didn't sink in what Arcade style meant. I am an addicted follower of Colin MacRea rally and thought to race a ferrari across the US would be cool. I was wrong. The games is to car racing what space invaders is to "Battlefield". The landscape moves instead of the car and you have these idiotic stages like impress your girlfriend with how many slides you can do. Total rubbish. Not anyones fault but mine, but I live in Ireland and got it shipped through Florida so it is a costly mistake. 
 Polarity: Negative
answer:

True
