The addition of three different paths was suggested by Falstein and added about six more months of development time, mainly because of all the extra dialogue that had to be implemented for the interaction between Indiana and Sophia.[1] Altogether, the game took around two years to finish, starting in early 1990,[26] and lasting up to the floppy disk release in June 1992.[34] The only aspect Barwood was not involved in at all was the production of voices for the enhanced "talkie" edition released on CD-ROM in May 1993, which was instead handled by Tamlynn Barra.[26][35] The voice-over recordings for the approximately 8000 lines of dialogue took about four weeks, and were done with actors from the American Federation of Television and Radio Artists. Harrison Ford was not available to record Indiana Jones's voice, so a substitute actor Doug Lee was used.[36] The "talkie" version was later included as an extra game mode in the Wii version of the 2009 action game Indiana Jones and the Staff of Kings,[37] and distributed via the digital content delivery software Steam as a port for Windows XP, Windows Vista and Mac OS X that same year. The versions on the Wii and available on Steam have improved MIDI versions of the soundtrack, along with both voices and text.[38][39]
