The base engine is a custom engine developed by Damizean and the Blitzsonic Team. The original engine's title was "Blitz Sonic", and it was meant to be a 3D recreation of the classic Sonic the Hedgehog games. The Genesis Redux project is an adaptation of this project. Sonickidnextgen/Sonickidnextgenesis has been "casually" working on the Genesis Redux project since February of 2011. The Next Genesis Engine was another adaptation by Sonickidnextgenesis, but it was canceled in October of 2010. The Next Genesis Engine, and the Genesis Redux project are both non-profit projects. Sonic the Hedgehog is owned by SEGA, and Sonic Team.
