I played through a few times, but felt there were some unexplained rules that I couldn't figure out; does each destination have a maximum cap on routes in and out? Are passengers generated randomly, or are there ways to increase 'my passengers'?
The game seemed interesting, I just couldn't penetrate the rules (or am terrible at it)
Some rule clarifications, at least in the current state of the game:
Only one route can go from one station to another, however they're one-way. So if you go from red-to-blue, that's blocked forever however you can go blue-to-red on a different route. I wanted to allow upgrading routes and upgrading-to-steal-rival-route but didn't get time.
So there's only 7 routes per station possible (one to each other station).
Passengers are generated with a method that is kind of like:
+2 per station per turn always (random destinations)
+1 per station for EACH ROUTE active, so basically you can benefit from building up individual stations at a time, as you'll get more passengers over time (but they still have random destinations, it's just to give a reason to build up a station over any other)
* sound effects
* music
* animations.
Advertised in game but didn't get time for:
* Transit types don't have maximum range like they should
* You can't upgrade your lines/overtake a rival line
