The soundtrack was released as an album on April 10 on iTunes and the PlayStation Network. The album is a collection of the soundtrack's "most important" pieces, arranged by Wintory to stand alone without the context of the player's actions. The album comprises 18 tracks and is over 58 minutes long. It features the voice of Lisbeth Scott for the final track, "I Was Born for This". After its release, the soundtrack reached the top 10 of the iTunes Soundtrack charts in more than 20 countries. It also reached No. 116 on the Billboard sales charts, with over 4000 units sold in its first week after release, the second-highest position of any video game music album to date. The soundtrack was released as a physical album by Sumthing Else Music Works on October 9, 2012. In 2012 Wintory released a download-only album of music on Bandcamp titled Journey Bonus Bundle, which includes variations on themes from Journey and Flow. The soundtrack itself was subsequently released on Bandcamp on June 19, 2013. An album of piano arrangements titled Transfiguration was released on May 1, 2014, on Bandcamp as both a digital and physical album. A two-record vinyl version of the album was released in 2015.
The first lesson West learns is that all industry and all institutions are under the control of the national government, a system which, he is informed, has proved to be far more effective than the earlier one of free, private enterprise because of the elimination of wasteful competition. These enormous nationwide political and industrial institutions are structured on the plan of a military organization.
Equality for all mankind is not a realistic goal in Wells's view. That, he believes, would mean a loss of individuality, and individuality is an inherent requirement of human nature. Similarly, competition is necessary to a thriving society. Taking what he considers a practical position, he sees the new society as divided into four classes of persons which he calls poietic, kinetic, dull, and base. There is a leader caste, called Samurai, which is drawn primarily from the poietic group, though some from the kinetic class may qualify. Persons who volunteer for Samurai membership must meet stringent requirements, both physical and mental; and they must pledge to conform to the rules of the caste, which forbid eating meat, smoking, drinking, gambling, and participation in public sports or entertainments. The Samurai furnish the World State with its administrators, legislators, lawyers, doctors, and other leaders. Furthermore, they are the only voters in the commonwealth. The male members of the Samurai are encouraged to marry women of comparable qualifications, and they are encouraged to produce children with the aim of improving the quality of the population. The lower classes of citizens, the dull witted, the criminals, and the deformed are exiled from society and prevented from childbearing.
