Motivation
We want to be able to pause the game.
Implementation.
There are several various ways to implement a pause behavior in a game; I think the one that I'm going to go for is a State Pattern which is probably the most theoretical of the common methods. A few disadvantages is that this will make the codebase larger than other implementations, but the tradeoff is that we save a branch condition for every object, which isn't a massive savings, but it isn't nothing either if we get into thousands of objects. Also more extensibility and a little more modularized code, so everything is kept nice tight little classes, which do very specific things.
To do implement this state pattern, every object will have a state manager, which will maintain which state is currently active by polymorphically swapping behaviors out depending on events it observes on a channel (a scriptable object IObservable) allowing cross scene state change communication.
