Wait, wait, wait. You say you put Gigant Space Turtule and bunch of whales into Sci-Fi Contest? Thats Purely fantasy man. You are disqualified! Also it's copy of Discworld idea, thats double disqualification! And that Turtule looks like from Mo' Creatures Mod... Triple one I say!
Well not quite. Altrought "Discworld" is a fantasy saga, and inspired me to make that happend I fallowed my own path in the end. Thats true, I am huge fan of sir Terry Pratchett work, and that map is form of my admiration towards his stories. I don't know how much of you read first Discworld. and i don't mean Color of Magic. I meant book before actual series. Its purely Sci-Fi story about artificial being that happen to be a turtule. And that's what my map shows. A.I. Turtule that carry biosphere for habbitants and is protected by spaceships that looks like whales. I could go into detailes how it work, but its not a point. I took diffrent aproach towards spaceship and spacestation idea.
Beside isn't Minecraft link magic(Enchanting, Portals, Potions) with science(Redstone Devices)? What would be more Minecraft that Gigant Space Turtule who is very mix of this two things?
To make it more in Minecraft spirit i looked at Mo'creatures turtules and elephants, yes iam guilty of that. I tried to match size of planet and it went well, altrought after you load world saplings may grow and destroy concept.
