Friends and I downloaded it, prompted by this post. There's a little bit of awkwardness and animation jank, but man, does the game get the core concept right.
Space is not flat, the ship feels like a near arcane contraption, rail guns should feel like they'll punch a hole in a small planet, and grappling hooks always feel good. These guys know what I'm looking for. The only thing I could genuinely ask for is a more true to physics flight model, but ultimately, I'll be too busy taking down fighters using a rocket launcher while gravity-booted to the nose of my ship to care too much.
I do want to state that the flight model has NOTHING on Elite. But otherwise, it is in a lot of ways a game which I wish Elite was a lot closer to.
