I disturbs me a great deal that the constellations and star systems are so far apart in this game. Other games I have played such as Distant Universe, Stellaris, and Polaris Sector. All these games have much denser stars in their galaxies. this allows for many more civilizations. In addition there can be longer waits to meet other civs, and more time to develop your own system. As to star types, why not follow the standard astronomical notation (O,B,A,F,G,K,M)? While there are probably planets around Blue and White stars the chance of any kind of Life developing there is negligible. It is commonly accepted that F, G, and K stars stand the best chance for Life having evolved on planets orbiting them. It would be WONDERFUL if ES2 reflected this accepted scientific knowledge. Thanks for your consideration!
