Because the alternatives are having it in the discussion section, or having draconian rules about what exactly counts as on topic and somehow punishing violators.
We manage to do it with politics (which is a pretty far sprawling topic). Why not with subjects that are considered off topic.
Why in the world would someone want to leave the possibility open of LW growing into another, much smaller, more sucky reddit?
What do you get when you put together Eclipse Phase, the science-fiction RPG of posthuman horror, and Maid, the light comedy anime-themed RPG? The answer, of course, is... Eclipse Maid.
The Ego (mind) Origins Table contains entries such as Blank ("You're a brand-new digital sentience, created from scratch to serve your Master"), Fork ("You're a scaled-down copy of your Master's own program. You have so many identity issues"), Uplift ("The Master gave you intelligence to serve him. Were you animal, or something weird like a plant?"), and Offspring ("You're actually a larval posthuman AI, serving your "parent" or another Master as a form of vocational training").
The selection of Morphs (physical bodies) includes ones such as Chibimorph, Giant Flying Space Whale, Spideroid ("This Morph resembles an armoured crab or spider the size of a small car. They're designed for combat and reconnaissance, but a hardware glitch causes Egos sleeved into them to become curious and philosophical"), Braincase ("A brain in a jar; you communicate using a built-in video screen with a picture of your face on it. While sleeved into this Morph, your intellect is vastly expanded, but you're easily tipped over"), Nekomorph, and Spectator ("A hovering metallic sphere with numerous camera-eyes mounted on prehensile robotic stalks. It's equipped with eye lasers for self-defence"). Special Morph qualities range from Blushes Easily ("This Morph turns red at the least provocation - even if this makes no sense whatsoever") to Solar Powered ("Efficient, environmentally friendly, and useless in the dark").
Possible Masters for your maids range from sapient starships to planetary minds to hive minds. You might enjoy reading the PDF even if you didn't know anything about role-playing games.
