By the time you've created World 5 or series III, I'd recommend experimenting Thyme scripting. It will make mechanics overall better and functional. Scripting is overall, hard (considering your possible experience), which is why I will let you do whatever you want. I would also uncheck the "Draw Borders" box on certain features. I would also diversify and use more colors than what I would call "basic colors" right next to the color picker. Overall, the series are a good idea, but you executed it poorly. I am sorry if I was harsh to you.

This is great and I love this series, but I also do agree with the Thyme scripting thing because the mechanics arent that good.
