Such a great ride... A driving sim done right.
The pacing is perfect. The trucks never feel slow, the paychecks never feel like cheats, but the game also never drags. There's almost always something new to buy after each trip, and taking a bank loan means that you can get a nice fleet of trucks from the start. The AI drivers will never bring as much money as you can by driving yourself, so you'll still roam the roads of Europe in your tuned monster, while you rub your hands each time an employee brings in some cash. Trips range from a few minutes short to hours long, but there's great diversity and choice and you can specialize anyway you want. Do you want to take the slow and short route? Or do you prefer to stay fast on the highway?
Buying expensive garages allows you to teleport to their locations between jobs. And you do get penalized for traffic violations, but it never gets frustrating. The towns are small but they do feel like the real thing. And since time is scaled, you'll usually prefer to stay out of traffic lights altogether.
It will take you some time to find things which could've been improved, but there's nothing game breaking. And even after you've pimped your truck and own garages in most towns, having more money than you can spend, taking a 2 hour job that takes you all around Europe will still be enjoyable. There's nothing quite like it in any other game.
