As one person stated on the comments for patch version 1.60, I think it would be fun to be able to play your own fleets while using the ‘control option’. Just send a challenge to your own username and play like that. That way you could have custom battles and nobody would be cheated. Kind of like a sandbox mode. It would get rather stale to play the same dozen-or-so single-player missions several dozen times. I am not sure if that would be difficult to code, but it is just an idea. Let me know what you think.
