The Castle Doctrine is the new "home invasion MMO" from cult game designer Jason Rohrer (previously: Sleep is Death, Passage, Chain World). It portrays a rather bleak world in which you must place traps to defend your home, family and life savings from an onslaught of burglars. At the same time, you must invade other players' homes to steal their life savings, in order to buy more expensive traps and tools. The more money you gain, the more attractive target your home is, so you better be clever in rigging up those traps. It's fiendish, brilliant, and currently open for public alpha at 50% of the full price. Rock Paper Shotgun has some early impressions: Part 1, Part 2.
Jason Rohrer's Sleep is Death (discussed previously) has been awake since Friday, and one thing is certain: This is not a game. It's improv theatre. And though it costs $14 to participate, sitting in the audience is free.
