Programmer Mike Tsouris will eventually release the Give Up Game
engine for the general public to develop against and use for rapid
prototyping of 3D game scenarios.
Documenting the entire engine, which was written from the ground up, is
a large task. Various articles will pop up on elements of the engine, and
as soon as there are enough to reasonably explain how to get off the
ground with the engine, the engine will be released as an open source project.
Stay tuned for updates.
