Started new game, EVERY road is a main connection. Dead end? -> Main connection! Road in middle of nowhere with no connection to everywhere with a lenght of 10 metres? -> Main connection!
Want to upgrade the road with tracks for a tramway? Well fuck main connection.
Want delete the savegame? Main connection! (just kidding ;D )
In 3 weeks are my semester test, and for relaxing train fever was the best game. 🙁
