In an interview with GamesMaster this month, Shigeru Miyamoto said that it’s “very likely” he’ll return to ideas that weren’t realized with the GameCube – Game Boy Advance link system.
Nintendo originally revealed the functionality at E3 2002. It allowed players to unlock modes, extras, and other content. One of the first games announced to support the functionality was Pac-Man Versus. Miyamoto noted that it was “a really interesting game”, but “it was rather hard for everyone to own four GBAs at the same time.”
Miyamoto told GamesMaster:
“I think it is very likely. I cannot tell specifically what ideas I used to have at the time which might be realized this time around. But as you might recall, at one of the E3 shows several years ago we showcased a game of Pac-Man Versus, which was a really interesting game. Unfortunately however it was rather hard for everyone to own four GBAs at the same time.
“But at that time still it was not very easy or accepted. [Now, with Wii U], it’s not just creators outside the company are finding fascinating possibilities to be able to realize a game dream come true.”
