Suicide Junkie: Yeah, exactly that sort of thing. I think it would necessitate seperating out ground combat from space combat; invasion in the space combat phase would simply be a dropping-troops sort of thing. Ground combat would be a turn-end thing. The game could export a list of unit IDs / what they have, and it could accept import lists of what units were destroyed. You could certainly go into more depth than that if you introduced regions or somesuch like MoO3, but that doesnt seem likely.
