How many GB is Illuminaria?

3 GB

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

Leave at least 9 GB free: games need headroom to unpack updates.

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

Command a swarm of intelligent robots in their quest to save the world. Mine resources, manage, and defend multiple bases. Go on expeditions, fight in auto-battles, research new technologies, and create your army of golems to bring back the light.
