[QUOTE="DMScott, post: 1035145, member: 11734"] A sci-fi gaming staple for physics-friendly multi-sun systems is to have the "planet" be the moon of a gas giant at or near brown dwarf size. A sufficiently massive gas giant can produce enough heat for long enough to allow a large moon to have an ecosphere, even when the gas giant and moons are far outside of a system's normal life zone, so you avoid the usual close binary problems of planets near the stars in unstable orbits. You can get a usable world this way, with [B]really impressive[/B] tides and weather. IIRC, both Traveller and 2300 AD had supplements with worlds like this. I dunno if you really want to get to that kind of scientific detail, though. Seems to me in a fantasy world, it's more important to have a good magical and/or religious treatment of your unique suns and moons than to get the science perfect. I'd just have strong tides and brutally hot summers, and concentrate more effort on special conjunctions and such and how they affect gods/dragons/powerful magic/etc. Definitely need some huge magical/religious implications for double eclipses.
