Bring The Legend of Zelda: A Link to the Past to the GBA was a stroke of genius. Not only is it the best LoZ game in my opinion, it is a flawless transition.
I was a little disappointed that this game wasn't introduced in the GameCube exclusive four game disc of Zelda games that came with the GameCube, but on the GBA, it is so much better. The fact that it is portable is great. The Zelda series on the GB systems have never been amazing, or very good. Bringing back a classic such as this shows me two things: Nintendo retro is a great thing, and Nintendo really knows how to get you to buy their stuff over and over again.
If you are a Zelda fan, don't finish reading. Get this!...why are you still here? Go!
