This game hasn't left my DS since I bought it.

This game is definitely worth every penny I spent on it. If you are a fan of Pokemon, you will love this game, as you can finally get ALL 386 Pokemon from the Kanto, Johto, and Hoenn regions wothout cheating, trading, going to Nintendo events, etc. If you haven't played Pokemon in you're life, this is a good place to start. It's simple, fun, and addictive. With new items and features, such as the Wonder Mail system, this game is good for even old veterans. The Wonder Mail is a cool new feature that is literally perfect for game forums, as if you fail a mission and lose in a dungeon, you can request help by posting your Wonder Mail, and if another person gives you an A-OK password, you can continue from the spot you died instead of going all the way back to the beginning of the dungeon. In terms of length, you could probably breeze through the main story (which, I might add, was much better than I expected) in 20 hours. However, the after-story is much longer. Add to that fact that you can spend a LONG time trying to get all 386 Pokemon to join you're rescue team. Overall, the game is excellent, and if you're bored and are waiting for a game system (like I am), this game will absolutely help pass the time.
