DESC: "Pok?mon Crystal is to Pok?mon Gold and Silver what Pok?mon Yellow is to Pok?mon Red and Blue. It features several minor upgrades from its predecessors, but in essence it's still the same game. The classic Pok?mon formula of adventuring, collecting, and battling is at a series best with Crystal. This is one of the best and most addictive role-playing games for the Game Boy Color.The most notable feature is the selectable female trainer who has her own set of animations and backgrounds. This is a great option for female Pok?mon fans who were previously stuck playing the game as a male character. There are also subtle improvements to the cell phone system, HM moves, and prebattle animations. Rival trainers' phone calls are now more plentiful and pragmatic. HM moves, which are required throughout the game, are available at the push of a button--you'll no longer have to navigate menus to use these moves. Lastly, seeing a Pok?mon's new animation makes encountering new creatures more fun than before."
