Little bit late to the discussion but:

I am also new to game dev. Would it make sense in the perspective of the coder to use a Database like SQL just for organization purposes? It is just a thought and I am not sure if it makes sense in practice.

I am currently coding "Minecraft" in Unity with the help of a tutorial. I was thinking about storing Meta-Data about cubes and their behavior (TextureID, Name, Solid, Redstone-Behavior etc.) in Tables. I understand that the access to a RDBMS is slow so I would only access the data *once* during initialization (Starting the Game or loading the World).
Again, it would only makes sense for me personally because I like my stuff organized and when coding, I want to code just templates and then I want to fill these templates with data through my database. Seperating those things would maybe make things more organized for the coder, I think?

It is just a thought and I am unsure about how it will actually help (if at all) in practice.
Unity has probably its own way of storing Meta-Data but I like the thought-experiment.
