imagine if you will, a fairly dry survival crafting game in which you live in a bunker and must periodically venture out to scavenge food, set up turrets for attacking monsters, etc
now, your computer inside the bunker has a game-inside-a-game on it which is a charming farming sim of undeniably greater quality and scope than the survival game you're playing. therefore, the object of the game becomes to keep your bunker secure so you can play the farming game more.
now, once you achieve the highest rating in the farming game, a secret shop inside it unlocks, and one of the novelty items you can purchase is a game console, giving you access to games-inside-a-game-inside-a-game. most of the games for it are typical mobile shovelware, but one of them is a highly polished, extremely brutal precision platformer with amazing level design and production values exceeding that of the survival game and farming sim combined.
it is only at this point that the purpose of this entire contrivance becomes clear: to create the most deranged speedrun community the world has ever seen.
