Re: Top 5 Champs books of all time
I think it's the timeline that sold me. In addition to giving the actual history of WWII, it gave a side-by-side timeline of how that history could've included superheroes AND a timeline of "uh-oh, the Nazi's won" for those pesky parallel timelines.
And while I think the heroes and villains provided were a tad too tongue-in-cheek, they were all solid characters. If you wanted to take your WWII campaign a bit more seriously, you could drop the "Doberman" angle and still have a pretty sharp Anubis-empowered villain. Aside from that, they were awesome, top to bottom. Dr. Bonsai and Origami Girl, the Ex-Patriots, Veltro... They've all stuck in my mind as iconic as Grond and Foxbat. All from just one book.
As an added bonus, it was a nice primer on life during the war too, just for education's sake.
