Chrono Trigger

Chrono Trigger silently tracks early actions and cites them later in its trial. Its trial raises your actions from the game's opening. The payoff comes from the game recording what you did without telling you.

Explicit choices announce themselves, often with an on-screen notification, so their consequences are hard to make surprising. Silent tracking lets a game spring an outcome later. Metal Gear Solid's Psycho Mantis works the same way, reading how often you save and how many traps you sprung. The source puts it as "the game can secretly and silently track your actions without you ever realising it".
