Yes coloured circles that glow. The map is so stylised anyway I can't be sure that the green one you refer to is meant to be a gas giant (relative dimensions are waaaaay off if it is). And theres what by that defintion is a star in the top middle with nothing in orbit around it, which is the same size as several rocky-looky planets on the map..gragh.Dalton wrote: Colored circles that are glowing? Not to mention the other gas giants I can spot that don't appear the same - namely, the green and white one on the lower left, and the one that looks akin to Jupiter on the upper left.
However I agree with your point that it doesn't quite seem right (I didn't actually notice as many gas giants around the "suns" first glance so the difference you mention I didn't see). Brown Dwarfs or similar seems a lot more reasonable now though, and they are more common than actual burny-bright type stars. I don't know if their gravitational forces are actually much less though so that might not solve the main problem of too many stars in close space).
(The other problem is that with that many stars in close proximity - continuous daylight pretty much all year round, and particularly in the central stars world, probably too high surface temperatures for humans as a result.)
