An unusual adventure game that came out of nowhere last year and garnered immediate critical acclaim, Chants of Sennaar is set in a Tower of Babel-like structure. To climb higher, you must explore it and solve puzzles primarily based around decoding the game's fictional languages, as you play a traveler who moves between the various civilizations that live in disparate sections of the tower. Figuring out what to do requires decoding non-verbal cues from NPCs as well as spotting clues in the environment, like illustrated signs. As you progress in the game, you'll fill a virtual notebook with translations that, if correct, will reveal the deeper narrative. Obviously the experience is slower and more introspective rather than action-based, but if you can get on its wavelength, it's a meditative experience.
