How else would a determinedly geeky guy survive a trip to Ikea? By pretending it's an adventure game, and writing a detailed walkthrough:

IKEA is a fully immersive, 3D environmental adventure that allows you to role-play the character of someone who gives a shit about home furnishings. In traversing IKEA, you will experience a meticulously detailed alternate reality filled with garish colors, clear-lacquered birch veneer, and a host of NON-PLAYER CHARACTERS (NPCs) with the glazed looks of the recently anesthetized.
