Very nice supers universe with actual time progression, rather than Marvel/DC "floating time".
An extensive history built to a jumping off point for your own campaign.
As usual, the characters manage to feel inspired by existing comic characters without ever feeling like rip-offs.
The Bad:
Some key players are still left undefined.
The editing could have used much closer attention, as there appears to be two pictures that were swapped, at least one missing picture and noticeable typos.
