How many genres could thrive without the most compelling parts of their gameplay? Would a Mario game live up to its iconic standards without the refined and thoughtful platforming? Would a survival horror-style game be able to get by without a sense of foreboding doom in the air? Could gamers buy into a Grand Theft Auto where you always had to obey the laws?
That question is somewhat misleading – It’s a common developer tactic to defy expectations and convention midway through a game temporarily. It keeps a player’s attention and forces them to think outside the box. By restricting a first-order optimal solution, a developer encourages its players to embrace the full potential of the gameplay available to them.
