[quote=Roose Hurro] With a binary star, the most important thing related to any planet in such a system would be: Is this a "close" binary or a "distant" binary system. To throw in a further wrinkle, how about a binary planet? Around a binary star? Each planet with its own species/culture/tech-level. Perhaps very similar, perhaps very different, depending on how these binary worlds interact with each other and with their binary suns. [/quote] I have thought about close planets in a similar situation before but never thought to apply it here. I would love for that sort situation a it adds so many more layers of depth.
