I would like to opt to have a partial or completely different opponents selection than my faction to pick from. I'm not expecting this to be a game option, but it can be. Sometimes it would be better if the opponent were different than players to one player. I'm going to used two for the example. OK the air wasn't using all the star bases, but it did need to have the gorernors on. So in modding it made sense to remove star bases for the air, but if the player picks were different  you could leave star bases. And leave the governors off. There is two ways to do this. Just have the opponents and players different, or connect the positions together, so whichever one you pick it would eliminate the other. The modders wouldn't have to balance between what the air could do , and player. But now they would be different making for possibly better mods.
