I suspect not many videogames have officially licensed fungus, but it certainly makes sense for Avowed, an RPG where you spend 50 hours in the shoes of a hero who has mushrooms growing out of their face.
Thanks to a company called North Spore, you can now own your own little piece of the Dreamscourge, with grow-your-own mushroom kits where fungus literally bursts out of the chest cavity of an infested skeleton.
And then you can eat it! It's $30 per kit, and there can be blue, pink, or golden oyster fungus inside—all ready to grow edible mushrooms.
They're pretty substantial boxes, and with proper care you should get two harvests out of a box, and you can even repot them to keep them going after that.
North Spore was kind enough to send me a kit to check out for myself, and though my mushrooms haven't erupted yet, so far the preparation and care has been agreeably simple—you basically just open the front of the box, cut an X into the plastic to expose the fungus to air, and then remember to spritz them with water using the included sprayer bottle a few times a day.
