Is it not possible that Urban games will go for a complete new genre?
According to this article, a reference is made to tram tracks in their next game – “We will also treat you with a widely requested improvement initially developed for our next game: Tram tracks can finally be electrified and therefore get the long awaited catenary.”. This would imply that their next game is also going to involve transportation of some sort. With luck, it might even be “Transport Fever” – Train fever with boats and planes and many of the often-requested improvements.
