One universe, many galaxies linked by a "hyperwarp" method located at the center of each galaxy. Each galaxy has many solar systems that can be warped to and from each other from a menu, but each solar system is just planets, moons, and asteroids surrounded by a skybox at infinity, where a sun is painted at one end, but is not reachable. There is gravity on each planet, but the gravity at each planet is the same, which is odd.No heavy or bouncy planet gravity, which could have been really nice, and incredibly easy to implement. You cannot throw your ship in orbit. If you don't keep your thrusters on, you stop, so you can't maintain a high speed without burning fuel. This game is more exploration than space simulation.
