So, I felt it was a bit underwhelming at the end, just a message saying you have ascended to god hood etc and connected to the shroud. And then you press "BEGIN" and the game is over and everything explodes, and while it sounds cool it really isn't that much, but at the end every star simply becomes a blackhole, which tbh it did give me a sense of accomplishment, standing there at the end of the game, looking at each system, and each time you jump into a system you see a mini-explosion, and then zooming out and seeing everything as a black hole.
However I think it would have been even better if at the center of the galaxy they would have added like a giant black hole or something, but oh well!
