I just wish the game didn ' t selfdestruct in the endgame . 1 . Performance Too many cities with 50006000 population and game slows down to a halt . 2 . Game doesn ' t build large streets . so unless you supervise each city at every moment , at some point the cities will grow so large and still use tiny streets , causing total gridlock . 3 . You have to plan 150 years ahead . Always have to build longest stations , biggest bus stops . because upgrading 100 years later almost never works . 4 . Have to rebuild and redesign your bus routes and industry routes . When a city gets too big , your truck stop that used to be in the outskirts is now downtown and your 50 trucks cause roadblocks . Same with buses . Your bus routes become overcrowded to the point of 100 people waiting permanently on each stop . The game doesn ' t give you enough high capacity road vehicles to deal with it .
