How many GB is World Climate Lab?

2 GB

That is less than the typical Simulator game, which needs about 4 GB.

Leave at least 8 GB free: games need headroom to unpack updates.

The figure is the storage Steam lists as required for this game, not a measured download.

World Climate Lab is a real-time planetary climate simulator. Import your own terrain or sculpt a world in the topography editor, then watch a living climate emerge from physics: winds, oceans, cloud bands and ice. Every climate is calculated, not painted.
