What Is It?:
Any in-game decision that is not really an option.
Why It's Stupid:
Why are you asking someone if they want to play your game if they are already playing it?
The Guilty:
Any game that touts its vast dialog choices and multiple endings that are dependent on a single event that happens before said end.
Even More Stupid:
Creating hours of additional game content hidden behind the no-choice-but-to-not-save-the-world option that no one ever knows exists.
Creating hidden choices that no one can see and then boasting about it.
