Mario + Rabbids Kingdom Battle creative director Davide Soliani wanted to make a Game Boy Advance version of The Legend of Zelda: The Wind Waker.
Soliani revealed on Twitter he and Ubisoft artists Fabio Pagetti pitched making a demo for a GBA version of Wind Waker back in 2003. Soliani even had Pagetti mock up the pixel art (below) to help sell the idea to Ubisoft and Nintendo.
