I was just thinking wouldn't it be cool to have another game where the focus was a single planet?
It could sort of be a planet sim game, except you'd have to fit into the empire as well. For instance you may be told to build a quota of ships ect.
On top of that you could have all the aspects of GC2 affect the planet. IE your planet could get invaded, and there'd be a tactical battle.
If you lost, you could manage the resistance fighters. Just a thought...
