How many GB is Techtonica?

15 GB

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

Leave at least 23 GB free: games need headroom to unpack updates.

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

Techtonica is a first-person factory building game set beneath the surface of an alien planet. Work alone or in co-op to build factories, gather resources, research new technologies, mold the destructible terrain, establish a base of operations, and uncover long-forgotten secrets.
