Survival vs Creative
In MineFortress there are two types of gamemode for Fortress: Survival and Creative.
Survival mode in Fortress has a limited amount of resources and land available. Pawns are using wooden tools.
In Creative mode there are unlimited resources, land, all blueprints are unlocked, no crafting and smelting. Colonists are using diamond tools. This gamemode is good for creating beautiful-looking colonies and fortresses.
However, both of them need houses or structures to make specific professions or increase amount of colonists.
