My new city in A-Train 9. I hope that A-Train 10, if released, will have the more advanced technology of 9, the complex timetables of 9, and the more sophisticated city and passenger simulation (including tourists) of Tourism. It would be the perfect mix.
A-Train 9 is too braindead once you understand the formula. It's basically a timetable simulator with 1-minute accuracy for mega train autists.
