how about instead of doing an era that is rife with comic book heros allready like WWII, why not try going into a new direction, like americana heros in the era of westward expansion? i mean come on, look at the list of heroses from this time, Paul Bunyan (axe tanker), Pecos Bill (storm powers), Danial Boon, Davie Crokit (both natural blasters), John Henory (twin hammers), in fact you could even say Jonny Appleseed (plant powers). lets not leave the villans out with such as The Jersey Devil, and Typhoid Marry, maybe even a PvP taskforce/zone looking for The Lost Dutchman's Gold Mine.
