This really does not sound healthy. The game is released, for a certain amount of money. If people don’t like what they get for their money, they simply should not buy it.
But by now gamers have been so trained to expect to endless content treadmills and all their ilk like mtx and battle passes that publishers/developers get egged on if they don’t work on their game 24/7 and forever.
Generally speaking it’s impossible to define a standard for how much output is “enough” for a developer.
Management always wants to extract as much as possible.
Well actually there is something of a standard:
Manor Lords is sold as Early Access. Meaning it doesn’t reach the “enough.”
