How many GB is Portal: Revolution?

13 GB

That makes it bigger than 93% of Puzzle games we have measured.

The median Puzzle game needs 1 GB; the largest tenth start at 10 GB.

Leave at least 21 GB free: games need headroom to unpack updates.

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