What's the point of 0 class planets? Given 0 class planets have no use it would be better not to render them. This would make it much easier to find the habitable planets. Also it would make the solar sytems look a lot more dynamic then 5 planets in a circle around a star. Second, why are all the planets in the same orbit? Planets need different orbits or they will eventually merge. That would be a fun planetary event. Too bad both planets would be totaled. So how to improve Gal Civ II's solar system model?
