Thank you for the link, that's exactly what I was looking for. I see the point that a single developer does not have to focus on maintainability so much. And if it works for him -- as it obviously does -- more power to him. But for me, I do not think I am mentally capable to reason about my program if it has to many globals. If I can have as much as possible local, my mental model also can be local. I am very new to gamedev, so this way of thinking may not be appropriate in the long run.
