I agree that we're good for now on backstory.
I think I've managed to absorb the essential parts of information about Freedom City. I do see what people mean, there is a lot of marvel stuff mixed in (and the references are quite obvous).
The power levels (of the heroes) are quite a bit lower than I was expecting. I think I'd expected the freedom league to all be in the higher PL range (I realize that a few of the characters are drowning in points). With a few exceptions most of the heroes don't seem to be optimized either.

And I think I counted at least three teams that said: We are the fantastic four (Atoms, Factor Four, Larceny, Inc.).
There are also a lot of "basic slots" that aren't occupied. In addition to lacking a proper mutant analogue (the claremont academy includes a lot of references to the x-men, but it seems to basically be the teen titans to me).
In some ways that shows a lot of restraint to my mind. Players get to play some of the "core" characters (the Spider-mans, Wolverines, Hulks, Dardevils).
There were a few powers I saw get used a lot that I wasn't sure about. Powers that aren't present in comics normally but make a big showing.
There are at least three sonic manipulators (Sonic who is actually fairly failful verison of Static but without the intelligence, the Majestro and the Silencer AKA the Punisher analogue). Are there any sonic maipulator/heroes in the comics normally? (Banshee/Siren don't really count in my mind).
Teleporters (sooo many teleporters), some people, (Magpie) can teleport even though it doesn't make much sense.
Healers (only two really, both females); slightly irriating but maybe D20 requires more healing...

Our group is quite a bit more powerful than I was expecting (from a PL/power point stance anyway).
