Let’s add “planets” between the worlds, just between the ones that get rendered in the sky. Fill them with asteroids, comets, new mobs, abandoned space stations, etc. Then let us build spaceships that can travel to these spaces and through to the next world.
We could just travel to these spaces to mine those asteroids, or to traverse to a new world, or to build a space station with supplies and fuel!
There should be no atmosphere, you’ll have to bring your own. There should be no gravity, don’t forget your grapples.
This would open up all new avenues for things like spaceship tools/weapons, skills, revenue streams like taxi services, fuel shops, ship building. People who REALLY want to feel alone could do so. Giant builds could be seen from the planets on either side of the space.
Maybe even some PVP designated areas or events where we could have our epic space battles for glory and bounty!
Let me know what you think!
