Was this game by any chance inspired by Indonesia?
I ask because I have a game design on the backburner that has some similar mechanisms, and it was inspired by Indonesia.
I have players owning both industry (farms) and shipping (rails), and my industry works the same way too -- they are built in the polygons between rails and players may initiate shipping from any of the nodes that lies on the corner of that polygon.
The game had a twofold 'inspiration'. Partly finding out about the odd history of the Daitou islands, partly from the mechanics of an early prototype for a train game I have been working on for some time. This game could be regarded as a simplification of that still underdeveloped train game. I think the only similarity with Indonesia is that there is farming and transport, but it works quite differently.
The biggest difference has got to be the lack of microwave dinners.
I don't get it.
More specifically, from the rules for Indonesia:
Siap faji mergers take place between a rice and a spice company. The resulting company produces microwave meals, called "siap faji". This is the only instance where two companies producing different goods can be merged.
