I agree with you to use guide book because of being busy life - job, family and friends. Impossible for me to have enough time to focus on my own without guide book.

Two weeks ago, I won eBay Metroid Prime 2 Echoes for just $20 after shipping (compare to used game for $30), and realized that game is very hard than original, I decided to get guide book, searched through eBay and lost bets from there and I surrender. Decided to go EB store near my local mall, and saw the very last two-year old copy of Metroid Prime 2 official guide book, it is excellent condition. I grabbed it and came to clerk - he scanned for price.. and it cost one cent!! The clerk said it’s free, and i took it home without having a receipt for this! What a sweet deal!
