From SCS Software:

1. 18 Wheels of Steel: Across America
2. 18 Wheels of Steel: Pedal to the Metal
3. 18 Wheels of Steel Convoy
4. TruckSaver
5. 18 Wheels of Steel Haulin'
6. Euro Truck Simulator

There is already a good list on this Web site.

I never heard of "18 Wheeler American Pro Trucker" so I do not know what to think of it.
