Without solo plays PG-HQ would be a very lonely place.
Peter's success with PG Uber has turbocharged shared plays, which is wonderful, because I do think head-to-head PG is the best way to play, but many people are not able to leverage that or dislike the online experience which I wholly understand.
Different members engage with PG-HQ in different ways, and that's fine.
All contributions are valid and valued.
