Working on games is cool cause they're antithetical to clean code. I'm sure some people will argue but clean code relies on systems that obey a set of distinct rules. Those rules are almost always absolute
So you start your game with your clean rules. In context A you can do B but not C
But an unfortunate part of game design is that the most interesting powers you can give players are the ones that break the inherent rules of the system. So inevitably you'll wind up with a bunch of code that works around your baseline rules and that always turns into a goddamn mess
