Depends on what they do with this game and what a future one would be. If they do anything like or even close to AL's dark drama ending, then it's not likely to go down well. People would still support them and they probably wouldn't lose that many patrons, but their reputation might take a knock if they have more sad, depressing endings in this game.
As for their next game, if it's another one with a real-world setting then it will probably do OK, but I have a feeling that the long DnG game in this episode was practice for the setting of their next game. That might go down well with some people if it's a DnD, GoT, Witcher type game, but it wouldn't be my cup of tea so I'd probably skip it and I'm sure there would be others who feel the same, especially since it opens itself more to dark, tragic themes than even AL or BaDIK.
