This I what made the 1990s era games so full of non-critical bugs AKA "glitches". The ceiling of complexity was raised waaaay over that of the previous generation of tech, but the techniques used by developers didn't advance nearly as far. So you have a lot of if this value == this number, load this scene (OoT) or if this value is greater than this limit, cycle it back to the lowest possible value of the range (Civ, Nuclear Ghandi) Now, bugs in big games tend to be critical crashes because the tooling and techniques have standardized and caught up to the complexity ceiling
