Driving through a muddy stretch of road leaves the truck looking like it's actually been somewhere. By the time I reach the next town, the wheels are filthy and there's another delivery to sort out. The smaller roads keep me paying attention, especially when the weather turns and I can barely see through the windscreen without using the wipers.
The full game is already unlocked in this version, so there's no need to deal with a limited trial. I can take my time exploring the map, changing the license plate, and getting used to different traffic layouts. Sometimes I end up driving through the night just because the headlights look good against the wet road. The cargo can wait another minute.
