We need it because this game have streets full of traffic. People could choose a metro etc. This game got subway alike wagons already. Bussrail is like a light-rail thing even. So, a Light-rail system with support for underground stations would be great.
But Avenues is important! Look at Cities In Motion 2 game. They have that. Or buss lanes that works.. or have an option of putting tramtracks in the middle of a 4 lane road. Anything really. In 1980s, Train Fever gets lots of traffic cues… something must be done!
The new Cities Skylines game doesn’t have trams at all! Still I think that the models in Train Fever for cars, trams, busses and trucks/trains is way better. So I just hope that Train Fever will deliver on the last things. Please!
