Capcom Developed Two Zelda Games
Believe it or not, before Hyrule Warriors not every Zelda game had been developed by Nintendo. In fact, the Game Boy Color titles Oracle of Seasons and Oracle of Ages were developed by teams at Capcom. Nintendo still oversaw the project and made sure the design ideas fit within Zelda, but if you felt the Oracle games were a little different, that would be why. Capcom also handled much of the development on the Game Boy Advance title, The Legend of Zelda: Minish Cap.
