This looks cool, but the pricing is absolutely insane. I saw $10-30 per session. Dming is a lot of work, sure, but that is a steep price. I don’t know many people who would pay $120 a month to play DND.
Keep in mind that we're speaking of building games totally hand crafted for the players and the characters they built, if done properly. Even if using a module, not two games are the same, because GMs build around characters, and players may get the story off-rails. It doesn't seem expensive to me, we're in luxury territory.
It's not that much when you consider that the the IRL group we where paying £2 to £4 dues and a couple of drinks and food so I was spending £15+ a night last year.
Ands that counting the cost of buying books figures etc for the DM
There's a fascinating change in willingness to pay between between digital and physical products!
I used to DM a weekly game. Every Thursday night our group would get delivery, at $10-12/pp, plus beers, etc. Once we moved to a remote session, I adopted Roll20, and was trying to decide if the $5/m was worth the extra file storage :P
... I was going to comment the exact opposite. If a session is 5 players and $20/session, and lasts 4 hours, then the GM is making $25/hr and that doesn't even include prep time!
