This game is hugely worth your money whether a fan of the Pokemon series or not. Essentually remakes of Gold and Silver, you start of as a young protagonist in a small town, and have to select a Pokemon from the Proffeser. Then you embark on a journey throughout the region, catching and raising your Pokemon, as well as thrashing some noobs and evil guys aswell. Familiar stuff? Sure, but it`s better than ever.
With loads of new features such as the Pokewalker, a small pedometer which ultimately speeds up the leveling up process and makes your Pokemon love you, not to mantion the ability to spend your 'Watts' on Pokemon and Items. Other features include the fact your first party Pokemon walks with you, the awesome new Pokethlon (essentually a collection of 10 basic, but fun, minigames) and the introduction of the Hoenn and Sinnoh Pokemon which were not available in the originals.
Overall a fantastic game, perhaps to say the best current DS game - well worth trying out.
