One fun thing would be to raise the abstraction level of the game.

How would it feel to only interact with your base/economy/army via prompting and face someone doing the same.

Would words per minute replace APM, what would the meta look like etc. Would you be able to adjust the system prompt for your "army" to suit your play style?

I get the feeling you are approaching Hesse's Glass Bead Game.

I’m sure it would be fun at first, but it would quickly become frustrating and repetitive.
