I figure I would mention that some of CA's greatest work has been implementing ideas from different titles in the series within new titles that they develop. And with the advent of the mod managing community, this can be a good way to experiment with tools like that.
But I like to grow as a player and, personally, I think that includes facing the occasional human player. It reminds me of my time playing shogun 2 and where I could have a player drop in for battles. I think that paired with a bit more accessibility in mod manager such as a multiple profile manager, it could make add a control and tool control to players that would just make it a complete gaming experience.
