Generating the setting and the characters, and playing a good deal of it takes about 2-3 hours.

So far everyone who’s tried this has had nothing but a good time with the game.
Everyone who hasn’t tell me stories of how a rogue neon genesis evangellion DVD killed their dog.

He’ll certainly be missed.

Half-elves have something of a precedent in LotR and such, but I think other half-breeds would’ve been the kind of thing Gygax would’ve written long diatribes against in Dragon magazine.

What I would like to see is rules for making characters that were adopted by another race’s culture, a la Carrot from Discworld, a tall human with red-orange hair who was raised by dwarfs.

Also, isn’t the minotaur in greek mythology the offspring of human and a bull? There’s an idea, half sheep, half human woolietaur! Good low level encounter I think.

Dwarves: Find humans too hideous to marry? Lets face it, dwarves come off as as sensual and sexually interested in the world around them as a 95 year old nun. I suspect that dwarves just aren’t that interested.
Halfings: Due to the traditional descriptions used for halflings, I suspect the subject of “half halflings”, ignoring the linguistic pain, were not included because Gary Gygax felt like a pedophile whenever he thought about it. Since he didn’t wish to think of himself as a rampant sexual abuser of children, half halflings were not included.
Gnomes: As above with an additional level of kink.

One could also make a good argument that just because man will boink anything doesn’t mean that man can successfully reproduce with anything. There is some mercy to this given that buggery laws were put in place for a reason. “This is my half sheep son.”
