After purchasing and playing KINGDOM HEARTS, I got addicted. However, after advancing rather quickly in the game, I got stuck between Monstro and Atlantica. I scoured the Internet, but it soon became a hassle to visit the net anytime that I reached a point I couldn't get past. So, I broke down and purchased the Official Strategy Guide. I'm really glad that I did. This is an awesome strategy guide! Without it, I would not have beaten Kingdom Hearts. The information contained within has also helped me beat 2 out of the 4 super bosses (I have yet to beat The Phantom and Sephiloth). Advanced gamers may not find this book useful, but just about everyone else who plays Kingdom Hearts will.
