Did someone mention Blade Runner the game?
The game is affected by both your choices and the game's choices set before you. This gives not just the ability to make choices but also the ability to react on the fly to choices set before you. In one game you might be shooting a replicant, in another it might be a human. They may run or turn and fight. You may be able to kill a character now and save yourself a fight later. It all depends on what elements the game has set and what you choose to act upon.
But that's a different game and neither here nor there.
