What’s the point of All In if it doesn’t lead to anything else?

Help me understand something. If All In is simply a one and done show, what purposes does it serve besides making Cody Rhodes and his buddies extra money by charing WWE type prices for an indy show?

Appreciate your thoughts as always.

​The point was to prove an indy could draw 10,000 people in the US without TV promotion.  And they've done it.  Considering that the highest ROH ever drew was a couple of thousand, it's pretty goddamn amazing and they're gonna make BANK on the merchandise that day, I bet.  Good for Cody, and I hope he continues to stick it to Vince.​
