The Mandate Engine is intended for use in exploratory strategy games that work in single player. Multi-player is not supported. It provides features from RTS(primary game type, complete support), City Building, RPG, SIM, Grand Strategy, and Society Management genres. Games on the engine can pick and choose among any of the features provided.
Just an update about the current status of the project.

Currently I'm just getting XML documentation up for the provisional release, basically just all the features that fit really nicely into the original purpose of GAE, which I forked. Layered upgrades, a better experience based level system, and other stuff like that. The more exploratory strategy, as opposed to RTSish, features are left out of the documentation and not as stable.
I'm also working on a demonstration faction with all the stuff working on various units while still being semi playable gameplay wise. This probably won't be interesting to anyone not used to Glest/MG/GAE.
