A documentarian and novice game-maker dedicated his 2018 to designing a game documenting an impactful Terence McKenna traveling experience to the Amazon. True Hallucinations: The Game puts the user in control of McKenna during his true-life adventures journeying to La Chorrere in the Amazon rainforest. The game attempts historical accuracy and features mushroom and butterfly gathering, I Ching philosophy, Amazon river boating and tripping out.
To play the game you’ll need to support the game-maker’s Patreon (the game-maker also has produced two doc films about McKenna). Or for the gist of the game you could watch the narrated walkthrough for free.
