Fair point, Taslios, in fact for me, once you create a Commonwealth, any tourism that Commonwealth makes should go largely, if not entirely, to that Commonwealth and only a small, very small bit go to the Player because heck, the Commonwealth don't want tourists visiting those weird cousin planets that, officially, are part of the same civilization but heck, who cares, they're dumps and miles and miles and "are we there yet?"s repeated ad nauseum from the back seat away?!?
Also agree that planets should not create influence/tourism money until a building has been completed, whatever that building is. If a planet has no building, it can't really make anything and certainly without a tourism or influence building it can't realistically say "Come One Come All To Sexy, Sunny BinaryToast II!"
