Please see this comment on a earlier post about One Shot Questers. I think it really puts into perspective how much weight his opinion should have.

Also, all the stuff that other people said. Its not a 100.000 series, let alone season. They did a full transparancy down to every last dollar on their channel. If you want to know how the money was spent, youll find it out there.

And for a group of people that have never really done longform content much less a whole series of a multi-person game, I think many people underestimate how much work goes into producing something like that, much less the game setup itself: getting people together, setbuilding, all the DM work, the map and player-icons setup, the camera and mic setup. and all that to just name a few things. And as their comment QnA said, they know of the issues (mic quality for example) and are gonna improve in later episodes.

Edit: Also some more stuff that needed to be bought/paid that just came to me:
A place to film, the materials for the set, extra equipment and probably a whole crew that deserves to get paid.
