How many GB is Obsidian?

3 GB

That is more than the typical Point-and-click game, which needs about 2 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.

Obsidian is a first-person 3-D graphical adventure/puzzle game, in which the player controls scientist Lilah Kerlins, who has to stop artificial intelligence Ceres from recreating the world.
