Cutscenes can be memorable for many reasons, such as their emotional impact, their humor, their shock value, or their artistic quality. Some cutscenes are so iconic that they have become part of gaming culture and history.
Which one is burned into your memory?

Ending A already hit me hard, but in retrospect it made the other endings hit me even harder, when you finally understand what really happened.
