Re: Time Frame for Appearance of Superhumans
My default setting closely mirrors the history of comics with super heroes (as opposed to pulp-style masked weirdos) first appear in 1938. I than have plot rationales to explain/justify the various generally accepted "ages" of comic history (Golden, Atomic, Silver, Bronze, Iron, & Modern. It also includes a Pulp era that predates GOlden). This gives me a setting I can use for any era of game that has a sense of historical depth and continuity.
