How many GB is Crimson Theory?

10 GB

That is more than the typical Adventure game, which needs about 5 GB.

Leave at least 17 GB free: games need headroom to unpack updates.

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

Trapped between dreams and reality, you wake up in an abandoned house. Strange notes appear—written in your own handwriting. But something is waiting beyond these walls... where the real nightmare begins.
