GAMER LOUNGE 20XX (NO CASUALS!!)

Well yeah, but it's not official. Or on a console. And allows you to program stuff.
An official Zelda Maker would likely be nothing like it other than the fact that they both intend to replicate Zelda.

It may not be on a console, but it does have its own scripting language.  I feel like anything Nintendo would make wouldn't quite have the same amount of capabilities, but would just be notable for being official.  ZC also lets you have whatever kind of graphics you want, whereas an official one would only have a select couple of official styles to choose from.
