#4 Nostalgia will draw in the fans
All you have to do is read any brand of social media to find legions upon legions of wrestling fans who staunchly believe that the wrestling they grew up watching is somehow better than what is on today.
It doesn't matter if the promotion is Mid South, the NWA, or others, there will always be people who carry a torch for what has been left behind.

In particular, there is a lot of WCW/NWA nostalgia at work on the social media pages of wrestling fans. Bringing back Halloween Havoc would be a way to cash in on the nostalgia and remembrance of these long time wrestling fans.
Even fans who never watched the old WCW events might be intrigued enough by a revival of Halloween Havoc to tune in and see what all of the fuss was about.
