1) What am I missing here?
2) Are all planets under 50% quality hardwired by the game engine into always run negative or near negative? I can't think of any other reason a 17% and 48% planet pull in the same revenue.
3) If #2 is true, is there any reason to colonize a <50% quality planet other than establishing system sovereignty? Should I just not bother colonizing <50% planets in systems I already control?
I do it for resources, if I really need them
the other 3) Is the culture % value of a planet just a synonym for development %?
4) Regarding luxury goods, is it the case that they are entirely useless beyond increasing your own planets' development rating? I ask because "foreign trade" seems to only ever bring in less than 0.5% of my annual income, even when I have FTA's with 20 other nations. They also don't add anything to planetary revenue (I tested this with the game editor, stripping a 300 billion pop planet of all resources).
pretty much so, yes
5) How come the occasional planet has 130% culture instead of 100%? I can see now visible ruins, buildings, or listed effects to account for this.
never seen this but the in the planets and bases screen that colony has a development breakdown, can you post a screenshot for it so we can check it?
6) Does the Expansion Planner's "Your demand" column only pertain to shipbuilding demand? Or does that column only show shortfalls rather than demand? I ask because all my luxury demands seem to be at 0.0k for my massive empire, even those for super-luxury goods I do not have any stock/sources of.
luxury needs in the expansion planner is not yet really clear, it may be that the game doesn't consider them needed. For sure "Your demand" column does not only pertain to shipbuilding demand, shortfalls is the best explanation so far
