Building a game world starts with choosing how its maps or terrain will take shape and what form the output needs to take. Compare generation method and map dimension, then look for seed control and custom assets that suit the kind of creation work you have in mind. Engine export and other export formats help you weigh how results can move into a game project. World Machine, MapMagic 2, and Gaea are among the options to consider. Free-plan availability and paid-from pricing add cost context; weigh those alongside the creation controls and outputs that matter to your workflow.
