Now to the actual game:
Fun:
The game keeps me in check (but a matter of taste), mainly because the game is not for the "in between". The journey takes loose one hour. In addition, you have to very many keys & shortcut keys noted otherwise you always need to read the manual. For "simulation freaks" that is certainly good but for ordinary players Währe simplified control desirable (I already played in the mode easy).
Graphics & Ambiente:
For graphics, I can report rather little positive. The only good thing for me are the changing seasons and the bus itself. The textures are nice and sharp and everything else is nicely animated. Otherwise, the game stutters in places very strong in spite of my very good PC system (Intel Core i5 2500K, NVidia GTX570 16GB DDR3 Ram and game installed on SSD). Also flicker the edges very much what bothers me personally. But what more disruptive is almost rammed everything and can be driven over the pile. Pedestrians can easily be run over etc. without "punishment".
Control:
The control is relatively "vague" what should probably go for a bus but ok. The one negative I have been only the many buttons and the complicated shifting into reverse gear.
Conclusion:
I would recommend the game to all those who cherish the good graphics no value. Also you have the highly complex control like. The graphical glitches and the game's performance may be so improved by a patch.
