Quoted from jfh:

This seems to be a common refrain from the operators I know or have heard from. Munsters simply isn’t earning as expected. Most home buyers will say “who cares?” but everyone should be asking “why not?”
Approachability of game play only goes so far for a game if it doesn’t earn for operators. Most aren’t going to wait around for code to get better (if that’s the problem). They sell the game and move on to something else and maybe buy back down the road in if there is a significant improvement. Operating pins is all about ROI. Munsters isn’t delivering.

Quoted from aingide:

Agreed.
I think that a part of the reason Munsters and, to some extent, Black Knight were greenlit was to let these two designers work on their dream themes. Stern is at a place where they can afford to take a few chances to keep the crew happy.
