Zelda Maker Already Exists And You Can Play It Right Now
Remember when Nintendo first announced Super Mario Maker and everyone started speculating that maybe Nintendo would make a Zelda Maker next. Nintendo was too slow. Someone else beat them to the punch.
Justin Sink's fun little project isn't the only way to make your own Zelda games; if you fancy yourself a junior programmer, you might also want to check out Solarus. It sounds like Nintendo might not be making its own version of this kind of game, so we'll have to make due with fan projects like these.
