During a practical at the Friedrich-Alexander-University Erlangen Nuremberg Daniel Bonrath and Michael Baer started the work on the i6engine, an event driven realtime game engine written in modern C++. As prototype for the engine the arcade racer Tri6 was designed. After the practical the two students continued their work on the i6engine and added many features until its first public release on GitHub in June 2016. Since summer 2014 Daniel worked almost alone on the i6engine until he stopped development on it in January 2017 in favor to switch to Unity to faster progress with the tower defense game Elemental War.
