Popular sim title Euro Truck Simulator 2 has shifted more than 13 million copies in almost ten years.

In a post on its website, developer SCS Software revealed the milestone, adding that it has also sold over 80 million pieces of downloadable content too. Euro Truck Simulator 2 was released on January 16th, 2013.

"Euro Truck Simulator 2 hails from a different era of the games industry, a time when PC games were mostly released in a box onto retail shelves. Our initial retail release of ETS2 took place during the autumn of 2012," SCS wrote.

"Its incredible success, during the first few days of release, was totally unexpected for us. And, as we watched the game hit the number 1 best-selling spot in the charts in Germany, the UK, Poland, and France, little did we know the game would become such a phenomenon."

The developer continued: "Today, the huge player base and community, our #BestCommunityEver, is a fantastic inspiration for us to continue the journey forward, expanding our truck simulator universe and evolving the fidelity of our games. Euro Truck Simulator 2 has proven to be a success story beyond our dreams, having sold over 13 million copies during its first 10 years, and Steam reporting over 80 million DLCs purchased, from small cosmetic packs like paint jobs to major world expansions.

"We could hardly ask for more. Still, we do hope that Euro Truck Simulator 2 has at least another decade of further growth in front of it - there are so many features will still want to implement, and so much new stuff we plan to bring you, so back to the celebration."
