Nested isn't a game. It's hard to even call it a text adventure. At first glance, Nested seems to pale in comparison to developer Orteil's other notable creation, Cookie Clicker. But with each click, diving into another sub folder, digging ever deeper, you realize that the game's simple description - "A Simulation of Everything" - couldn't be more accurate. Nested is exploration distilled to its purest, most minimalist form in a simple text format. An infinite amount of things to discover, from the grandness of multiverses and space to the abstract plane of thoughts and memories.
Nested is randomly generated, so one could browse through its endless worlds forever. It's quite literally an endlessly fascinsting experience. Descend through ever-more-detailed folders, from space, to planet, to continent. Forgotten lands, ecosystems bustling with life, civilizations from the primitive to the futuristic and the outright bizarre. Dig further still, into the memories of a village chieftain or the thoughts of individual nanomachines. Venture deeper, into the chemical make-up of individuals and landscapes and objects and you'll find even more subatomic universes to explore, an endless nesting doll of life.
