Oh, I know, I don't doubt Caleb's ability to turn any game into what he wants it to be, but I was just surprised that he was thinking about Better Angels, based on the tone of it that I perceived without having read the book or .pdf.
Also, Caleb if you were thinking about Zombies, and wanted a twist, you could check out Unhallowed Metropolis. It's a zombie game set in Victorian Steampunk England. It's gotten great reviews. You might have just thrown up a little at that suggestion, and if so, please just ignore it.
