If you want add a D7 based or 3D engine to the listing please leave a post with a demonstration in #Submissions

* Engines are listed from the
oldest to newest & most advanced

* A ton more, and I mean a TON more engines were made over the course of time, we're still in the process of discovering all the Classic Engines, and there are more Revival Engines but they don't meet our quality standards.
