(I've made similar threads in the Marvel and Spider-Man boards - thought it would be fun to do one for the X-Books)
Simple question: What's your favorite X-Men Event
1. Mutant Massacre
2. Fall of the Mutants
3. Inferno
4. X-Tinction Agenda
5. X-Cutioner's Song
6. Fatal Attraction
7. Phallanx Covenent
8. Age of Apocalypse
9. Onslaught
10. Operation Zero Tolerance
11. Messiah Complex
12. Second Coming
13. Age of X
14. Battle of the Atom
15. Other
Mine would have to be either the first, Mutant Massacre, or the biggest, Age of Apocalypse. I'm also a big fan of Second Coming despite most people placing that well below Messiah Complex.
