It's a terrific listen courtesy of the Dev Game Club podcast. Day of the Tentacle is the primary subject, but a broader discussion about adventure games emerges.
What makes the interview particularly worthwhile is that the hosts are Brett Douville and Tim Longo, who worked at LucasArts around the turn of the century, when a developer's assignment was pretty much guaranteed to be a Star Wars title. It's interesting to hear the different perspectives from the four alumni who were involved in different eras and concentrations of the studio. More crucially, Jake gets namechecked.
