Rebel Galaxy is pretty great actually. Its a more accessible version of that Elite Dangerous space sim. You should try it out. Thea is one of those empire management sim 4x games, but it also has a roguelike spin to it, so you basically lose the game with one bad encounter. It's quite controversial within the 4X community. There's also a card battle system which people seem to either love or hate. Rebel Galaxy is good though.
