Honestly, how good of a game wasn't Call of Cthulhu..
"Now...at my end...I can fully see.
My last case opened in me a new fear...a real fear...a fear of myself, of what I am...and of what I have always been.
All that I was, is now lost. Hope? Purpose? Pleasure? All meaningless.
I now walk in the shadows between worlds...and it is there I have finally glimpsed upon what lives in the dark corners of the Earth..."
