Just picked it up as well. It's very good, but the map is already starting to feel small, even though I'm only like level 3 and haven't put a single point into Long Distance yet. The map needs to be doubled in each direction (4x the area) before it's big enough to even support the game mechanics. For now I'll just level up the other skills and leave Long Distance untouched.
Other than that I like it. It's going to be great once they get another 3 - 4 states out. The graphics are quite good (not GTA 5 but good enough). The AI is as crazy as ever. Most of the time, merging means closing your eyes and praying that no car decides to ram your trailer from behind (damaging your cargo and giving you a fine). Sometimes you have to slam your brakes on an on-ramp because a car is stopped and trying to merge by slowly inching into traffic. At least there are no roundabouts with kamikaze drivers like in ETS2. Reversing seems harder than ETS2 - those trucks had crazy tight turning radii due to the cab-over design.
