If you can't believe a developer would build an entire game around big rig trucking, check out these screens of SoftLab-NSK's Rig 'n' Roll — the only big rig simulator that covers all of California.
Players take the role of a young man in the year 2024 to drive ginormous trucks from one end of the Golden State. I guess that explains why there's not much traffic in these screens. In the future, they'll actually be done with roadwork on I-5 and the 101.
I'm actually sort of curious about this game. Curious in a morbid way that makes me wish for truck stop mini games of an entirely inappropriate nature. Look for it on PC sometime this year if you, too, suffer from this curiosity.
