Hi i got some possible ideas for future uppdates in space engine. First of would it be possible to add caves in future uppdates or would it be to much for the engine to handle or does the game just works like that? And in the future you should be able to change time. Like our sun go back 4 bilion years and watch the sun and the planets form and go forward 50 milion years and see the earth no longer host life due to the sun increased heat. And make it work with all solar system depending on the stars. (you can skip supernovas and red dwarfs since whe dont know how they die). That was just some ideas but my main point is the time change to cause bigger realism and see how system change in time like a cold ice world becomes a terra if the start heat upp in 40 milion years. And then you can go back in time to see how it was then and go to current time again.
