This is both unrealistic and impossible in 2024. There's an almost infinite number of choice combinations that a player can make, some of which can enable access to unique / hidden content, and there's no way to test them all.

Imagine e.g. an easter-egg side quest that involves the player going into a brothel, but that only activates if some NPC notices you're wearing a specific piece of armor, which has a 30% chance of dropping from a monster that you don't strictly need to kill to finish the entire game.

Not to mention content patches, intentional easter eggs, scenes which should technically be inaccessible to players but can still be accessed due to bugs[1] and so on.
