Game overall is great. Graphics wise it's good looking, physics wise it's great feeling.
The game has mod support with which you can expand your horizons by quite a bit.
Features single player and pretty damn well working multiplayer. However multiplayer is max 4 players.
All in all the game is about transporting goods around the map. But we all know it's not that simple.
Honestly there's nothing bad about this game it can even run on the worst laptop you can find.
Only bad thing was the mess the developer of the game had with the publisher. Publisher didn't want to pay the developer for months if I recall correctly. So eventually the developer managed to achieve a few things like he took the code and published his own game "Mud Runner".
