It would be nice to have a localisation plugin that can set regional text, sound and images depending on the language-region preference like in unreal or godot. The localisation can be defined in a .csv (and other formats can be supported if needed). Providing localisation components can greatly enhance the user experience when setting up the scene,
eg,
If you need a ui text comp to be localised you can attach a LocaliseText component with the key to an Entity with UI Text component. The LocaliseText component system will set the UI Text component with correct string from the localisation data at runtime. Similarly we can have LocaliseSprite with sprite key to set the correct image on a sprite.
