Day 7: Most "Intellectual" RPG Owned
I don't think I own any of those? Well, okay, I might have acquired on in some bundle or other, but I'm not interesting in running games around some kind of highbrow concept. Or in exploring deep philosophical issues through roleplay.
Oh, having glanced at a few other people's thoughts, it's probably De Profundis. I'm not entirely sure this actually qualifies as a roleplaying game, being rather more of a self-contained Mythos tome. It seems to lack most of the possible qualifying traits, like decision mechanics, randomisation, chance, pattern recognition, statistics, tactical play, or any rules whatsoever.
