Default 'game' directory vs. custom 'renpy.game' paths for project portability

When establishing a repeatable development environment for complex Ren'Py 8 projects, asset management often requires a choice between adhering to the standard project structure or implementing custom path logic for asset loading.

The default game directory provides native portability across different operating systems because the engine abstracts the underlying OS paths. However, as project scale increases, developers may consider using a custom renpy.game path configuration to handle specialized asset loading logic or to separate raw source assets from engine-processed files.

There is uncertainty regarding how the base directory resolution behaves when these custom paths are used in projects launched via external launchers compared to the internal Ren'Py launcher.

• Does utilizing a custom renpy.game path impact the consistency of relative path resolution across different launcher environments?
• What are the trade-offs in environment repeatability when moving away from the default directory structure for asset management?
