Please go whine somewhere else. Yes, the game was released in an unfinished state, but at the moment the most annoying perfomance problems are solved and many game-play elements are hugely improved. At the moment it’s definitely worth the €20,- selling price.
They have said months ago that certain gameplay elements (railroad crossing, bridges etc.) are too deep coded to fix this in a simple patch. But these problems are not game breaking such as the performance issues from the release.
So if you dont like the game, go play your Transport tycoon, railroad tycoon whatever. But please stop hating around since the game doesn’t even matter to you. Thanks and goodbye.
