It is said that for every person who has inhabited the Earth, there is more than one shining star in the universe...In Nebula you will have to collect stars to position them in your galaxy. Stars come in various stages, from red giants to white dwarfs, which you can get from star clusters. You can get stars by investing Time or going to Chaos. Then you must position them in some orbit and constellation respecting the law of gravity. Finally, there will be objectives, both personal and shared, that can reward you, and also some stars without glow that will remind us that death is part of stellar life. Give life to your Galaxy and find harmony within your constellations. The stories that will be invented while you watch them will last over time...description from the publisher
