Too much leverage
The game was not satisfying the players and they were at their wit’s end.
As a result, the decision was made to change the main game to a completely new one. A few months later, a major update with a new main game was implemented.
But the players who updated to that version are furious.
“The game was more fun before the update.”
Whether this is really the case or not, unless things have gotten much better after the update, it is probably an inevitable situation that such voices will be heard.
From my point of view as an outsider, I think the decision itself is “not going to happen.” If you are going to leverage, it seems like something with smaller steps would be better.
