I've somewhat followed the RPG Maker program over the years to see it evolve into a tool some decent games have been made from, and now it looks like RPG Maker MV will come to Linux.
Thanks once again to SteamDB:
403874/name: RPG Maker MV Linux Depot
The Linux content depot is currently empty, so it's just begun. It doesn't meant it will release on Linux, as they could just be testing the waters here. Would be nice to have another useful tool native on Linux though.
I managed to find a Steam forum post asking about Linux support for games built in it, and it as usual had some idiots jumping in derailing it.
RPG Maker MV games are essentially wrapped up web-apps, so it shouldn't be too hard for the games to run, but I don't know what the editor is built with. It runs on Mac so it's at least possible it will come to Linux too since they know how to do more than one platform.
I will keep an eye on it.
