I have been playing it this weekend and it is amazing, the procedural planetary systems, the missions, the 21 or so ships (of various classes), modules to fit on your ship, missions and main story. It is also gorgeous and the ships have a cool aesthetic. However the best part of this game I think is the combat and its deviation from other space games. Basically you play on a 2D plane (you can't really pitch up or down) but the reason for this is due to the broadside gameplay, basically naval-style combat. It works so damn well in this game and it's super fun due to the tactical way you can approach fights and I recommend anyone who enjoys space games to check it out. It is also a sandbox that allows you to play how you want, piracy (there's also pirate factions), smuggler, bounty hunter, etc.
Here is a developer playing the game and talking about it:
