At the finale of Deus Ex: Human Revolution you choose which button to press to trigger one of its endings while an AI explains the differences between them. It was not a well-liked way to wrap up the game, and when just over six months later Mass Effect 3 came along with a remarkably similar structure for its ending we were all a bit baffled it came down to this. Three games' worth of agonizing decisions would all be resolved by the simple mechanistic choice of a button press?
It wasn't the only thing about Mass Effect 3 people found worth complaining about, but it was right up there. It remained a pain point even after the free extended cut DLC expanded the endings to make them a little more satisfying, and a fourth option where you refuse to choose was added to satisfy players who got to the end and wanted to flip a middle finger at the whole arbitrary concept.
