I see many games use jump scars or loud sounds to disturb the player or very gross things, but does that scare you? Does it make you not want to do something is that fear? I think one way to look at fear is the thing where when you don't want to do it, but for some reason you are compiled too. It's the trigger for courage or to say it another way the way to invoke your conciseness in times of the unknown.
What are some other ways to view fear? or what is fear to you?
