When I was a small kid, I simulated bus traffic in a city. I used wooden chips, sanded and painted, as busses and figures from board games as people. Busses had their actual schedules, there were stops with higher demand, people with agenda depending on week day etc etc. This game is like my childhood dream come true. The mix of puzzle and simulation nature sits very well. Its a game I could have never wished for but I sure as hell am glad that I was pointed to.
