Yeah, this should definately go to the games section.
Anyways, since I'm a Pok?maniac in my own mind, I do suggest the game if you have the time. Like the original Red, Blue, and Yellow versions, you get to explore the land of Kanto. Of course, it's been modified to fit the Game Boy Advance screen more fully. In other words, the land is slightly larger. You'll meet all of the older trainers, like the kid who complains on why you don't wear shorts, but there's new trainers you can battle as well.
Unlike the originals, you'll also experience much smarter trainers as well. In the originals, everybody, trainers and wild Pok?mon, will use their attacks randomly. Now, tougher trainers and Gym Leaders will actually use the moves that will give them the advantage, much like the two newer series. Not to mention that there's Pok?mon from the Johto region to capture and the new unique abilities that each Pok?mon has (introduced in the Ruby/Saphire/Emerald series). Finally, there's more to the game than Kanto. The storyline goes further than that.
To sum it all, up, it's the original games, except buffed up completely. If you miss the old games, go ahead and buy one of them. If you really have the time, buy both! I strongly suggest to buy the games since they remind me of the old-school games.
