How many GB is Unlocked?

2 GB

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

Leave at least 8 GB free: games need headroom to unpack updates.

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

Time is locked. As an interstellar being, you must visit the four seasons of earth and get time running again. Collect items, uncover secrets and right the wrongs in the universe! Includes a second bonus game, 'Blue Sky on Mars'. Journey to the red planet and enjoy a cosmic Sci-Fi adventure!
