Well, fan site Adventure-Treff recently tracked down Hal to talk about what his role will be on the project as well as his past work. Some interesting details on the new game are revealed, some fun LucasArts stories are recounted, and even some rare concept art for one of the canceled sequels to Atlantis is shared. There really is tons of great stuff here. But mostly, the living legend just spreads his awesome. The following quote says it all, really:
During the development of The Infernal Machine you said in several interviews that you don't find the classic adventure genre very interesting anymore. How do you think about this statement now that you are working on one of those?
Hal Barwood: I take it all back.
Read all of Hal's thoughts, and be happy.
