Of the choices I picked Capes and Babylon with a qualification. One thing that, in my opinion, Champions suffered from was it never had an actual playable campaign. We had an overwhelming cornucopia of individual pieces that could be plugged into a campaign. But no actual campaign.
If Capes and/or Babylon contained the standard what and wheres are what 99% of the "campaigns" out there, but also included an actual campaign. As in a series of plot's, encounters and coherent playable story. Pinnacles' Plot Point system is a good example of this. I'd snap it up in a heart beat. But if they were just another "setting" book, meh I have 5 playable cities and as of last week 4 teen superhero school/academies.
I don't need additional "settings". I need a pre-fab Campaign.
Correction, I need a pre-fab superHERO Campaign. No dark conspiracy, no mutant "fill in the blank" hunted hate'o'verse, no "semi-redeemed mass-murderer/psychopath just saving the world, no dark loner hitman vigilante with a soft spot and not even remotely a superHERO type game.
A good old fashioned "the good guys" saving the city/academy/world type of game.
