The tile building system is soooo nice! The music and art are fun, so the simple act of playing the game is fun. Now trying to accomplish the goal? It's hilariously convoluted, which makes the "take the money and run" button very appropriate!
And then I realized I could make one bus route connecting all the stops. That's why they pay me the big bucks $$$ Only downside is people have to wait a long time, just like real buses.
Another thing: For some reason, the game started me zoomed all the way in, I couldn't see enough of the map to connect almost any stops or even read the labels, so it was kind unplayable. I mouse wheeled down, which zooms out on most things, and nothing happened. Took me an embarassingly long time to figure out I had to mouse wheel UP to zoom out, opposite of most zooming in apps :P
