Don't get me wrong. I'm not saying I'd read the fucking thing. I'd rather gargle I just like big groups. All-Star Squadron is the other one which comes to mind.
There was an idea being touted years ago that the JLA should consist of every character in the DCU. I kind of liked the idea despite the propensity for it to be a wank fest, because you'd have occasions where the focus would be on obscure characters, and other occasions where you'd have the full team of a hundred or so characters in a situation.
