Great prices for the original game. Apparently the original devs are still committed to game and fix bugs.
From the website:
With this Steam PC key, you'll climb aboard incredibly detailed soviet inspired vehicles and venture across the rough and tough terrain motherland Russia has to offer.
WHAT THE TRUCK?!
Featuring a highly unique physics-based deformable terrain and water interaction technology. Spintires boasts a quirky new experience every time you play.
Winch yourself, or friends out of a mudslinging exercise and explore the depths of Russia, finding garages and fuel stations to keep your vehicle alive - carry logs and bring them to the objectives without becoming lost or stuck in the mud. Unlock and use more capable vehicles, or install one of the vast amounts of attachments available to help you along the way.
Offering a truly immersive driving experience, watch in amazement as your vehicle becomes entangled in trees, bogged down in mud or swept away by river currents.
