There's two PWGs.
There's where they started, basically to audition themselves to east coast indies. In this sense it was a failure. They all got a couple matches in CZW in 2005, and Super Dragon got to represent them in the ROH feud. But that was it.
But as they started to retire PWG became something else,
>>12773526 doesn't even understand why he liked them.
By sticking to the DVD market it gets them out from under contractual entanglement. It was the only place for a while that you could see ROH vs TNA guys, it's why they could use Lucha Underground guys and no one else could. With NWA, New Japan, MLW, TNA, ROH and AEW all having written contracts, if they actually put on shows again, PWG has endless unique matchups they could offer.
Some people criticize AEW for being PWG with a budget. And while they might have the same brand of humor, that's where the similarities end. Super Dragon would never waste a great singles match so he could cram half a dozen guys in a tornado tag.
