How many GB is Sister Other Paranoia?

3 GB

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

A dark visual novel created by the team behind NEEDY GIRL OVERDOSE. Overly sensitive to other people's emotions, the protagonist—a light novel writer—develops the ability to read minds, only to be driven even deeper into isolation. His sole remaining comfort is his younger sister, gifted yet lonely.
