How many GB is Morrigan's Isle?

20 GB

That is more than the typical Role-playing (RPG) game, which needs about 6 GB.

Leave at least 29 GB free: games need headroom to unpack updates.

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

Stave off waves of enemies that grow in strength and number as each night passes and defend the Tree of Life. Survive, harvest resources, craft armor and weapons, outfit helper NPCs, and build a base protected by auto-firing towers. Explore the island to find gear with the power of the Celtic Gods.
