Yeah, SotC hits on many of the character archetypes I'd like to include, but doesn't have quite as strong a hand with the setting. I'm specifically imagining an alt-history 1930s which, by default, is open to mad science/archaeology/masked vigliantism/etc.
For the limited world-building I'm particularly inspired by Monkeyfun Studios' "Spirit of '77." (
http://www.monkeyfunstudios.com/what-is-spirit-of-77/). In describing their fictional 1977 they do an excellent job getting the feel of the era down, without wedding themselves to every historical detail. I'd like to do a similar thing for the '30s with my hack.
For example: in Spirit of '77 Nixon has managed to dodge impeachment, the U.S. still has a military base in Saigon, and a sport called
"Rollerball" "Derbyball" is just as beloved as baseball or football. But, gas is still crazy expensive (for the time).
In my '30s hack, the world would have Tesla-esque scientists and explorers discovering entire civilizations beneath the planet's crust... all while the Great Depression is still in full swing.
