What do you mean by "classical"? If you mean more straightforward noir sets, then it was just because I thought it was easy for a GM and players to create that sort of thing on their own. I was just throwing out lots of ideas to show a variety of possible settings.
You are right that it could be easily hacked to be a solo or GMless game. I might need think about adding some notes about that sort of thing.
Maybe in the future I'll write up some historical noir settings and add those to the playset pack. Lots of fun options there as well: Berlin 1948 with the ashes of WWII turning into the Cold War, Los Angeles 1937 with Bugsy Siegel and Hollywood corruption, Tammany Hall era New York City, Elizabethan London with Walsingham and Christopher Marlowe , etc. etc. Once you pick a setting, it's really fun and easy to flesh it out into a playset.
