Spaceships were divided into many levels. The lowest was the one-star spaceship, which could only fly around within a single star system and had very limited functions.
Two-star spaceships could travel between star systems, but only through one star system at a time, so even within the galaxy, relying on two-star spaceships was very slow.
After all, there were countless star systems in the Milky Way, and flying from one side to the other took a long time.
Three-star spaceships were very valuable and could pass through multiple star systems at once. The high-end spaceships used by many of the galaxy's technology companies in the spaceship business were three-star spaceships.
Four-star spaceships were even more impressive. They could travel the entire galaxy at will, their normal cruising speed could reach 100 times the speed of light, and crossing thousands of star systems at once was no problem.
