Quick disclaimer, I wouldn't exactly call this a game. It's more of a program which lets you fly around the universe exploring real catalogued stars and planets along with procedurally generated systems filling in the vast gaps of what we can't see in real life. There is a flight simulator mode which I'm not familiar with using, I find most of my enjoyment flying past galaxies at warpspeed, searching for interesting looking star systems and planets to take photos of. For that, I can recommend Space Engine, but if you're looking for a game with story or objectives, you will have to look somewhere else.
