I was considering buying Zelda 4 Swords to play on my Wii. My question is whether it is necessary to have a Game Boy Advance to enjoy all the aspects of the game?
Yes, but I remember way back when it first came out my friends were screwing around with their Game Boys and trying to do something. Probably to truly play 4 player, or link the games I have no idea. I was like 10, can't remember. But in other words, it should work.
