This obscure Winsome Games offering is not their usual type. You acquire shares of train companies, but instead of building track and running trains on a map, you play train cards to city columns. You can run down your opponent's stocks by running trains - although I worry this is underpowered.
It's an ingenious little system, but it's OOP, the components are print-and-play quality and the rules are poor.
Deserves a print-and-play re-release.
