I was never one of the lucky few that got to play the original Four Swords game. But I was lucky enough to play Four Swords Adventures the way it was intended to be played. With the Gameboy Link Cable. Now you don't necessarily have to play it with the Gameboy Link Cable, but without it you wouldn't have to full experience. I remember while Four Swords Adventures was still new they sold the game with the Gameboy Link Cable with it. This allowed for interaction between the Gamecube and GBA. I never actually used the GameBoy Link cable until one day i plugged it into my Gamecube and I was fascinated about how whenever I went into a cave or something, it would show on my GBA. FSA was my freaking childhood, until I traded the game for Super Smash Bros Melee(I never got the game back btw) If there is a FSA2, the interaction between the WiiU and TV will be the same as the GBA and Gamecube. And with the new Nintendo direct, I can't wait to play Zelda online!
