Emotionally and/or Morally Difficult Decisions
Many games offer the player a wealth of strategic choices, often on a moment-by-moment basis. These can be a fun form of gameplay, but they don't cause the player to become a deeper person.
Here we're talking about Emotionally and/or Morally Difficult Decisions. The choices should not be easy.
You could find yourself with an infinite number of tough decisions when playing a game.
For instance, do you save your best friend or the villagers who have come to need you for protection?
Another example: The villain has captured your sister. To free her, you'll have to run a mission for the villain, a mission that may result in hurting an old man the very man who trained you in the martial arts you now possess. What choice will you make?
