Case study

openage: a Genie Engine reconstruction for Age of Empires games

openage reconstructs the Genie Engine used by Age of Empires, Age of Empires II and Star Wars: Galactic Battlegrounds. Its C++ engine and Python media converter use assets from the user's original games and convert them into openage formats. The author states that gameplay is currently almost nonfunctional while the simulation is rebuilt.
