GAE was originally started by Daniel.Santos, as a desire to create a special engine for the then-work-in-progress, Four Path Magitech, and started with offering auto returning units and other small enhancements, growing to eventually try to accompany the four path magitech. When four path magitech was abandoned, it was later picked up as an alternative way to play glest, and now is an engine with its own unique mods which work specifically on GAE (namely, Military and Malevolent Rising). To date, it is still actively developed by the GAE team, who's current active members include Silnarm, Hailstone, and Yggdrasil.
