Mate, don't get me wrong, but why do you make it so complicated?
Easy steps for RPG Maker MV Games:
1. Download RPG Maker MV Linux Launcher v1.62.

2. Copy the game's "www" folder into the launcher's folder.
3. Mark game and nw.js files executable.
4. Enjoy the game.
Other games which use TyranoBuilder as game engine, there you can use the nwjs-method to play them natively on Linux.
P.S. To solve your above permission issue you can use chmod. Open Terminal and type:
chmod -R a+x [drag and drop game folder and hit enter]
i appreciate you taking the time to try and explain this to me and show me an easier way , but believe me , i would love to use a less complicated method , i have also tried this method with the RPG Maker MV Linux Launcher v1.62
but it just dosnt start , i will try and explain the steps i took and would gladly appreciate any advice as to what i do wrong ,
1 first i make a folder and put both the unzipped game in and also the RPG Maker MV Linux Launcher v1.62 folder and open both ,
2 i then move the www folder from the game to the RPG Maker folder , and i’m asked to merg these , , so i do ! Maybe this is wrong ??
3 next i open proprieties of of the game desktop folder and the 2 nw present pack folders to make them excautiable also , ( i dont know where nw.js files are , so i presume that they are the nw 100 and 200 present packs ?) is this right ?
4 when i change the proprieties of the game desktop folder i get a untrusted application launcher box ,
i click trust and launch , at which point that folder changes into another type game folder ( or launcher or app or whatever its called )
5 i click this game launcher yoke , once , twice , 20 times , noting happens ?
Noting opens , noting runs at all
as for the other method like you said Open Terminal and type:
chmod -R a+x which i can do ( just about ) but i simply just don't know or can figure out how to drag and drop a folder into a terminal
