    Mandate Engine

    RTSish Game Engine

    ...The 7 games are all based on this IP: Children of the Thousand Suns: The Unaligned Mandate Each game combines a few different genres from this list and others: RTS, TBS, RPG, Sim, City Building, Breeding, Management You can also make mods of various kinds with support for all the features my own games use and possibly more. It's open source and free obviously. Most modding is done through XML files quite similar to the ones for other Glest derivatives. There may be some good scripting support as well. Currently for fun I am creating a Majesty like to play with since Majesty 2 sucks and Majesty one doesn't support easy modding. Changed the homepage to the GitHub since the repository here is being difficult and thus doesn't contain the source.
