Tried this on in VM Ubuntu and Mint and am pretty stoked, but in reality I'm a (novice) Manjaro user. That being said, it appears I will need to change only one thing in your script (the call to the package manager). I will try this later, primarily because I don't want to try this on my daily driver (just in case). Looking forward to this. Linux does have software with this kind of functionality (Gnome Games, GameHub, Nostlan, Pegasus) but nothing has quite the same... verve? Personally I'd rather have Launchbox as an AppImage or better a Flatpak/Snap (keeping it distro non-specific), but if you got it working in Wine I'll take it.
