Like the title says it would be cool but i'm lacking of ideas so you guys post in the comments what do you think that could be in the nebula and what we could find ^_^
Yes, let others come up with your idea for you... That said, how would you interact with them? What would their purpose be? Nebulas are massive clouds of gases, so they would be like gas giant planets, only bigger...
Someone mentioned unstable stars and "new stars" with young planets that are rich in ores. Nebulas are literally the birthplace of stars, so perhaps these "new stars" could appear in nebulas, which, for the sake of gameplay, are small and extremely rare. The sky would be very colorful too, both in space and on the planets. Any pyoung planet would have to be a lava type planet.
Yes, i didn't thought that way but actualy, it would be cool. Like the sky of frigid ocean biome but more colorfoul.
Imagine that you get an Upgrade in your tech menu that lets you wear two nano skins at a time, because the planets found in nebulas would have two hazards to deal with at the same time, there would be: Nebula Alpha - Requires Rad-Heat protection, contains "Alphite", which is used to combine Ferozium and Impervium Nebula Beta - Requires Rad-Cold protection, contains "Betite", which is used to combine Ferozium and Cerulium Nebula Gamma - Requires Cold-Heat protection, contains "Gammite", which is used to combine Cerulium and Impervium It may be difficult since those materials would be listed as Antimatter, so they can't be mined with a Matter Manipulator, there would have to be some way to obtain an Antimatter Manipulator or something.
