Off Topic, but related. speaking of custom game mod and map editors and builders
I have to say the PC is king and queen when it comes to custom level and custom video game design, of coarse I don't know if they have a mario maker for PC. But.
PC has even more free level building programs and accessories and the most free custom features for a ton of PC games
if you're like myself and designed things for the video games I've loved over the years, there is even YouTube Tutorials on how to use most of the game/mod/level builder programs out there
