Head on over to rpg.net and look for some reviews there. They have a very active set of forums, if you want to ask over there. My vague recollection is that the current Heroes/Champions is a multi-book system now. Back when I played (early 90s), "Champions" was the single-book superhero game and overall game system, and individual sourcebooks adapted the system for non-superhero genres (my group played "Fantasy Hero", for example).

Edit: And I also recall that the Hero/Champions system has changed hands a large number of times, so that may explain why the confusion in figuring out whether you're looking at current or historical information.
