Need help with a map.

[Preian2]

Hello there. I'm a big fan of MCSG and I love building stuff on Minecraft so I'm going to make a map myself when the new World Edit update is released. But i need to know something before I begin building and terraforming. When I make the world should I make a Creative or Survival world?Should I allow cheats or not? May someone please tell me how the world should be generated? Please excuse my terrible English.
