Do you have a couple of hours spare to watch someone else play Doom II? This video is worth it.
A few weeks ago an innocuous post on the Doomworld forums announced the release of MyHouse.wad. Players expecting to find a basic 90s-style level of a suburban home instead found a conversion of the game that pushes the engine to its limits and creates an experience much more like the novel House of Leaves than your typical run and gun Doom experience.
There’s something to be admired about the time, effort, and skill that goes into creating works of art like this with old-school tools.
