Additional World Size Settings
Current game settings allow for worlds of the following sizes: Unlimited, 100, 50, 20, and 10km. I would like to see some additional limits. Perhaps 500 and 1000km. A slider would be the ultimate of course.
Not sure if this is workable but I would love to have a smaller world size that still leaves a fairly large area to work with and hide in. At a larger size you would have the ability to introduce a small planet.
I may be incorrect but I would imagine this would ease server hardware demands yet still leave players with a decent sized sandbox with all the options.
