MTA:SA still reigns one of the ultimate GTA clients ever made. One of the reasons behind this is because its so easy to create and edit maps, whether you intend on hosting a server or making it available to other servers.
My suggestion for FiveM would be for a offline (and maybe eventually online) map editor as standard in FiveM, accessible via the home screen.
Through MTA:SA it creates a localhost server for yourself with just a few clicks on a dropdown, you can then within a menu, manage the map type, and basically every element ever.
I think its really important this comes into development as I really believe it will revolutionise FiveM as it did with San Andreas.
Here are some example images from Google to those of you who haven’t used MTA:SA map editor before. The ability to not only create custom maps, but custom gamemodes whether you want to implement .lua’s .etc or not is insane.
