the reception of Book Three, Realms. Voice recording for the third episode took place simultaneously in Los Angeles, New York City and London and was completed on 20 May 2015, shortly before the Book's subtitle had been announced. For various reasons, several developers, including the design director Martin Bruusgaard (who was on a parental leave), couldn't participate in the creation of Book Three, with only eight RTG employees working on the game full-time, assisted by several part-timers and freelancers. Since the first three books had suffered from graphical performance problems, RTG decided to develop Book Four in Unity 5 and to retroactively upgrade the previous Books to the new engine version in July 2015. The entire porting process took four months and cost the company between $100,000 and $150,000, due to a combination of factors, such as having to adopt new tools, to reapply all lighting effects to work with Unity's new "Enlighten" system, and to rewrite all shaders and scripts from scratch for the new engine version. Several engine patches that fixed critical errors introduced new bugs instead, eventually forcing the team to stop all work on Book Four until the finished port of the first three Books was released to Steam on 23 November 2015. The production of the game was completed on 17 June 2016, with the release of Book Five. RTG has, however, promised long-term technical support for the game, with four developers and several freelancers dedicated to the task in the months following the release. The patches planned for early 2017 included the German translation update for Books Four and Five, the remaining in-game backer rewards, and the Final Cut update that "upgrades the game to match the console versions". At the time of the Kickstarter campaign, the developers planned for it to become the final game in what they called "the Dreamer Cycle", but not in The Longest Journey series as a whole. This had changed during development, however, and Book Five was presented as the conclusion to the entire saga upon release. In October 2019, Red Thread Games have once again reiterated that "for various reasons, including licensing terms", they are not working on any projects in The Longest Journey/Dreamfall series. Casting Many characters from the earlier The Longest Journey and Dreamfall were re-cast for the third game in the series, including both returning playable characters.
