Scariest Game You've Played? Back in the day my buddy Todd, ran a Vampire: the Masquerade game for just me and our friend Barry. It explored some pretty dark things and while sometimes we responded with violence for the sake of violence (in our defense we were both Brujah Anarchs), the horror came from exploring the world we lived in (pun intended) and the creatures we had become.
A central theme, because of my character, became diablerie which contrasted with my initial concept for my character as a Vampire who fought his Beast and embraced his Humanity. But our journey through Chicago had me devolve into a being who embraced his Beast fully....leading to the ultimate crime in the world of the Masquerade and the blood hunt that resulted in it.
Strangely, we often played during the day, but in Todd's basement, time had no meaning and the shadows of broad daylight seemed to creep into our decisions.
It was a great game.
