With the upcoming price increase, I think it would be a little scummy to start charging extra for DLC. Any new content they want to add should just be free updates.

A-ha!, so I'm not crazy.

Ok, so after reading the last page here, I tried making a railworld, and sure enough, it looks like a much more "normal" map from what I remember. I'm gonna give that a try when I have proper time to sit down and play.
