Oh, here's a fun fact: If you choose The Golden Age (whichever one of the two options you pick), The Silver Age: The Tense Times and The Modern Age: The First Generation, then there is a Trinity (like DC's Superman, Batman and Wonder Woman). If you eventually get one of those options, then you have a chance to replace one of the stock members of that era's Trinity and become a part of it yourself.
For example: If you pick The Bleakest of Times, your actions can cause you to become a core member of the Trinity of that era before it is formed, replacing someone else. In this case, your actions inspire a ton of copycats and people look up to you, so there is a good chance that Baseball-Boy and Lady Flame will meet up with you to form the Trinity instead of going to meet with Strongman.
If you pick the Old West setting, then eventually you will become a legend like The Man with No Name, Pecos Bill and so one. Maybe you'll be considered the greatest bounty hunter of the west? Who knows.
In the 1891 setting, you can become as famous as Abraham Van-Hellsing as a great monster slayer, making your actions myths to humans and terror to the supernatural community, which includes the Hungarian/Romanian Vampiric societies.
In the Silver and Modern ages after either The Tense Times (Silver Age) or The First Generation (Modern Age), then you are inspired by the Trinity but can't become a part of it. You can however become their apprentices/sidekicks and maybe inherit their hero name after they retire, and that's not just concerning the Trinity.
In the Dark Age you can either define the edginess of the period (first option) or try to end the Dark Age and begin the Modern Age early (second option). If you succeed in the second option, you will immediately become part of the Trinity of the new era.
