How much prep is too much prep?

[4]

I'm looking to start up a Homebrew Superhero Universe to run various games in it (Using Mutants and Masterminds), I wanted to establish a history of said universe, create heroes and villains, organizations. You know, the works. I'm worried that I might over do the background info and either overwhelm the players or worse create info they will never read.

Any advice on what I should focus on, avoid or just general advice from your own experiences?
