Better Procedural Asteroids for better game play
The current way in which Procedural asteroids are place was good for the early game when the world was small but there is no real reason to go to any particular place on the map.
I recommend building a mini solar system, where there are asteroids belts where a planet's orbit would be nice ring that circles the map. Plus for asteroids near planets I recommend using Lagrange Points (see attached image) for asteroid placement location near planets. This would make the game more realistic, Plus it would force players in to area where they are more likely to run into each other.
