Game is very immersive just in current state and I think, 1:1 scale dramatically improve feeling of simulation (The Bus had something what missing for example in Fernbus or ETS 2) . I believe, it will be only better and better. Editor is fantastic, graphics and AI traffic very decent.
But after release of 1.3 version I have problem with constantly crashing on the Spandauer Str/Marienkirche stop from Alexanderplatz direction. I dont know the reason, but previos versions was very stable and practically without crashes. Otherwise game is very smoothly on my system with epic settings.
