Saying "Management is good" is the kind of example I'm talking about. What kind of management games? Is it an aspect of the game, or a focus? What makes the gameplay stand out from others of it's genre? Doesn't every game have resource management anyways? (Yeah, almost)
Management is a Genre of it's own.
What you have to understand about "Games" with "Gameplay" is that requires a Player Skill to learn and master and get Challenged on it.
In the case of Management Games that Skill is "
Optimization" through Efficient use of your Actions and Resources.
A good example of management game is
Bifrost as it has both the Challenge through the Debt to pressure you and your actions are substantial enough to matter.
Management Games tend to have a Debt as a premise as that is what pushes you to be Efficient, otherwise you would have no reason to be efficient.
A example of a game that fails at that is
Stive Conquest the Debt is poorly utilized and even if you decide to pursue it you can't use your actions efficiently depending on the situation and opportunities since the solution is right there from the start and doing something else is likely to be less efficient.
In other words there is nothing to "learn" to optimize and get better at that as things are already at the optimum, this is where most "Sandbox VNs" with some "resource management" tend to fail.
Another example is
Brothel King, it does not have a conventional Debt but it still has Wealth targets you need to reach.
It does not push you and pressures you to be efficient but your actions does have an effect as you can be more efficient and there are Events and Upkeep you need to properly handle, it is just a more gradual and grinding process as that actions are not as substantial as the interactions with clients are not as direct like in Bifrost.
An interesting case is the old Slave Maker game as that doesn't have a conventional Debt but it does have a Timelimit for training an reaching a certain state with the slave, money isn't as easy as only a portion goes back to you so there is proper resource management on top of the action economy.
