Vox
A surreal RPG with multiple settings¸ where each player plays both a character with voices in his or her head¸ and the voice(s) in another PC's head. It uses the PDQ2 game engine¸ designed by Chad Underkoffler. The core book includes four setting seeds: ""Facility¸"" a distant future sci-fi horror setting; ""Oversight¸"" a modern-day political conspiracy setting; ""Currents¸"" a 1920s Lovecraftian mad science setting; and ""Reckoning¸"" an alternate Victorian historical mystery setting. - A description from https://darkshire.net/jhkim/rpg/encyclopedia/ with kind permission of John H.
