Hello i'm new to this forum and learning various things to do game design.
i've read few books that related to game design.
but i don't understand how to measure the world size in numerical value.
like Starwars Galaxies says their world size is 45 km2 and Dark and Light says
their world size is 45,000 km2 , how can they measure correct size?
what's the base of those output?
on the other hand, i would like to ask that what should i write on design document?
since forum search is disabled atm, i could not found
please convince me about the basics, i'm just a student of development.
Thanks in advance.
