I too loved Secret Wars.  Yeah yeah yeah, it was what killed comics for a lot of old timers, the characterizations were off,  blah blah blah.  It was no worse a reason to get everyone together and fight than Stan and Jack had set up two decades prior.  

The plot is also similar to a Star Trek episode titled "The Savage Curtain".  I don't think I've ever seen a full Star Trek episode, let alone this one, but the wikipedia writeup is suspiciously similar.

I enjoyed Civil War a lot as well.
