And the directions are still pretty confusing. For example, I had no idea the debris' orientation mattered until I saw the examples. And what happens if there's a dispute about whether the debris is aiming at a planet or not? And also, can I keep a planet if I didn't roll a sun with it? I assume not, but it's not explicitly clear. And what's the difference between orange and yellow space debris? Also, the How to Play section indicates I should only keep planets and black holes, but don't I also keep stars so that my planets stay habitable?
The answers are there, but I agree that it could be quite a bit clearer.
> Can I keep a planet if I didn't roll a sun with it?
No - suns make planets habitable (see the Sun section); you can only keep habitable planets and black holes.
>What's the difference between orange and yellow space debris?
There is no difference between red and orange space debris (there are no yellow -- the colors in the instructions are slightly off from what the dice actually show). There's also no difference between yellow and green planets/suns -- take a look at the image in the article that shows all the dice laid out. I think it'll clear that question up.
>but don't I also keep stars so that my planets stay habitable?
That makes logical sense, but since the instructions specifically state to keep only planets and black holes, no, suns go back in the tube. I think the logic behind this is two-fold: One, since planets and black holes are the only metric for score, any planet that you keep has a star in its imaginary galaxy, so a planet that is by a player actually represents not just a planet but also "at least one star." Two, a green/orange die going back into the tube helps keep the game points flowing.
