I do wish they would consider giving some better feedback in the download system. Quietly failing is... a fail. When I click the link, nothing happens. Is it my browser ? Is it the system still being hammered by humble bumble?
I am certainly glad that there are many folks who might now give Pathfinder a try (awesome job on the twitch stream btw!) but I fear that this download system failure will make Paizo look bad to all these new customers, who may go away soured.
The thing with Roll20, the reason IMHO that it has been so successful, is that it is SO super easy for players to use. Go to the web site and play. That's all you have to do. The lack of complicated features is a feature in this case.
