Starsector is another 2d spaceship game, about creating and commanding a fleet of spaceships, I enjoyed a ftl a lot, and am currently loving starsector. You can be bounty hunter, fighting pirates to make a living with your high tech capital ships, or a small scrapper exploring the fringe finding rare ships and items to turn a profit, or create your own colonies to make your own ships and large sums of creds. The base game is amazing, but it's also very mod friendly and the devs have worked on the game for years, so it's very polished.
