My first truck sim, and I am lovin' it. The visuals are good and the weather effects and day night cycles are well done. I am using an xbox 360 controller and it works well ( with a few changes like setting the right stick to be the look around in cab view and some extra key assignments such as wipers and lights ), so it seems very configurable. I like the facility to play your own mp3's or even select to stream internet radio while driving. I am using version 1.1.3 on windows 7 and it runs fine, my PC is almost right on the recommended specs and it runs smooth and looks great.
The developers have done a really good job here, it is currently competing for my attentions with Forza Horizon which was released the same day and when you consider the resources and marketing power of the MS Forza franchise, the fact that I have spent more time with ETS 2 since they both arrived is quite telling.
I recommend it thoroughly. I must get back now, as I have some earth moving equipment to take to Amsterdam, and a ferry to catch.... .
