Hi,
I know that games made with RPG Maker MV can be exported in various manners. I don't know the complete list, but I am 100% certain that it is possible to export them in such a way as to create www/ folder and other files.
Even if game is exported for Windows, it can still be easily run on Linux. All we need : exported package.json file (even for Windows) and www/ folder with game-specific stuff. Afterwards we just need to follow a simple procedure (much easier than using Lutris or Proton ) :
1) Go to the game folder (even if exported for Windows)
2) Delete everything except www folder and package.json file
3) Download Nw.js for Linux from https://nwjs.io/
4) Export contents from this archive into the folder of the game (where only www and package.json remain)
5) execute nw with ./nw
I am not sure how difficult it would be, but I would appreciate it if you could figure out a way to export the game in such a manner (html5 or web-version?)
P.S. Think about posting your game to https://tfgames.site/. It will increase the number of people aware of your game.
