A game makes you think you can make a decision, but you really can't.
This is when a videogame offers you the ability to make a decision and then denies you any meaningful consequences for your choice. Imagine that you've reached the final climax of the story, or at least a minor one along the way, and suddenly you're presented with a list of options. After considering your choices, you decide to save, and then pick one of these and proceed to the end of the plot. Having seen the story play out one way, you then reload your save and pick a different choice, hoping to see a different outcome. Then you see pretty much exactly the same thing as before. Programming a real Branching Plot, even in a game with Multiple Endings, is time consuming and expensive, and becomes more so the further back along the timeline of the game you go. Consequently, something that a lot of developers will do is provide you with options, and then give you an identical or nearly identical gameplay experience without regard to your decision. There are several ways this can be done: A. You have multiple options, but there's only one that actually counts. All the others lead, slowly or quickly, to a Non Standard Game Over, or a But Thou Must declaration. B. You have multiple options, but all they do is make a minor cosmetic change to the story you'd play out anyway. C. You have multiple options, but as soon as you've made a decision something in the game will happen that invalidates your choice. In non-interactive media, this trope is usually covered by Morton's Fork.
