There were dozens of Acknex games published over the last 20 years. I own around 30 that were sold in jewel cases and DVD cases in Germany. Mostly shovelware and low budget products. And I don't own the millions of simulator games. In Germany there were shelfs full of simulator games in malls and supermarkets and many of these games were made with Gamestudio.

I can can write a list of older releases, but I don't know all of the simulator games and newer steam releases.
