Occasionally an ETS2 trucker myself, I remind you there is an alternative now, American Truck Simulator. For the li'l difference.

- ETS is nice, a relaxed, laid-back experience, good for recreation.
If you like ETS/ATS, consider OMSI 2 plus X10 Berlin addon. Most realistic bus simulator there is. Setting it up correctly can be a bit rough an experience, but the realism is superb. I lived in West-Berlin of that time, i know those busses and even the lines - I even can identify the flat where my old dentist was located. Physics, sounds, handliung and recognition value of the environment are superb. - Track IR recommended, also for ETS/ATS.
