Atlas, our trusty scenario editor, will be available as a user-friendly solution to customized scenarios and campaigns, comparable to the editors of the 'Age of' series (except maybe with less bugs than AoEIII's ). New units and other aspects of gameplay will require modding, which we've made as easy as we possibly can - made by modders for modders. That's not to say, though, that some nice person won't come along and develop a generator for things like random maps and AIs.
