The game is now
available on Steam, but it's Early Access. As I have enough games to play and enough games that are
still Early Access, I won't touch it now. Not even with a stick. Not unless it's on discount in a Steam sale (yup, I'm a man of principles). But there's
a nice preview on RPS, and it does sound interesting. Especially the words "spreadsheet balancing" piqued my interest. And krys is right, it does sound like Railroad Tycoon... and that's not a bad thing.
