18 Wheels Of Steel: Haulin' is a trucking simulator made by SCS Software. One is able to run in Canada and in the United States. This game runs on Windows XP, Windows 98, Windows ME and Windows Vista. Users with the retail box version should download a patch available free of charge at the SCS Software website - see the patch changelog available at that site. It is one of the most realistic driving games available in the United States. It has since been replaced by 18 WoS American Long Haul around Dec. 20, 2007. This installment adds more cities and has more realistic graphics than previous games in the 18 Wheels of Steel franchise. The ability to use custom soundtracks and save games during deliveries was added also. Choose from 32 rigs, 45+ cargoes and 47+ trailers.The game doesn't require a very powerful computer to operate reasonably well, but it requires an up-to-date graphics card (RAM 256MB, processor 1.4GHz, 128MB video card). 18 Wheels of Steel: Haulin' may be one of the most realistic trucking games on the market. Prism 3D may not respond on older graphic cards resulting in a game crash on the game's startup.
