Brian is back at it with another list opportunity, due to popular demand.
http://goodcomics.comicbookresources.com/2013/08/06/vote-for-the-50-greatest-x-family-stories/
My list is this:
1. Kitty Pryde: Shadow and Flame 1-5
2. Kitty Pryde and Wolverine 1-6
3. Excalibur 61-67
4. Wolverine (2003) 20-25 Enemy of the State
5. Pryde & Wisdom 1-3
6. Wolverine (1988) 125-128 Viper Wedding
7. X-Men True Friends 1-3
8. Mekanx 1-6
9. Generation Next 1-4
10. Kitty Pryde: Agent of SHIELD 1-3
I should have added the Demon Bear Saga from New Mutants 18 – 21, but that’s okay. None of mine are going to make the overall list, except for maybe Kitty Pryde and Wolverine.
The results start on August 21.
The list should be all over the place so my heart goes out to Brian Cronin, as he’s going to have a load of work ahead of him. Voting stops on the 18th of August.

I voted for Enemy of the State. And Mekanix was popular enough to make the Kitty Pryde list so who knows?
Thanks Greg for the response!
Enemy of the State was such a good storyline. Thought Agent of SHEILD was good too but it was more of a Wolverine story whereas Enemy of the State had a giant cast of characters.
