it appears that larger worlds will be less of a problem due to Large World Coordinates based on 64bit floating point precision. but still thats not the point.
were still talking about
- larger Space Games
- interstellar travel
- portals to different levels with different skysystems
- seamless travel to maps with totaly different physics
- having “insight” in to other maps without actually enterying them
and these are just the posibilitys that i can come up with from the top of my hat.
