Esprit Nouveau is a tabletop role playing game written by Harald Eckmüller, host of the 3W6 Podcast.
Based on the PbtA system, players take on the role of paranormal investigators in an alt-history Paris, in which the discovery of the Aether - plane of spirits and astral energies - has replaced the use of electricity. With this powerful technology however come certain dangers, as the thin veil that seperates the planes begins to be frayed.
