That method inherently requires a transition, and a transition separates the planets from the universe. It makes doing things on planets and doing things in space two completely different things, rather than letting them blend together seamlessly. After all, how could you bombard a planet from orbit if it technically existed in a different universe?
While that method was certainly considered, a lot of StarMade is designed to flow together as naturally as possible with no arbitrary changes, making sure everything exists and interacts in one cohesive universe. This assures that if you want to do something, you can do it, and won\'t be limited by arbitrary transitions.
This new method allows many of the benefits of a round planet while remaining in one contiguous universe, all while still keeping to the general StarMade feel.
Lag is obviously always a concern. StarMade was built from the ground up with reducing lag in mind and it still struggles some, mostly due to sheer scale. Attention to and the minimization of lag will not be overlooked.
