As you could call about 90% of our games Cargo, it sure is a broad category. It is hard to describe a Cargo game, the main aspects are that we service industries and we typically use the standard ML structure, but even that can have various results.

|A game with massive amount of hubs and also high amount of main stations due to many various industry types.|
