It's clearly a prank to show that Amazon is as cool as Google, but the reading of Article 57.10 the general conditions of use of its new platform Lumberyard to create video games is pretty... surprising.
The article starts quite normally (in the American way, that is) by listing the somewhat surrealistic conditions under which the Lumberyard service cannot be used, namely in systems that could endanger human life or safety, in nuclear power plants (to play at blowing up the planet, no doubt), in spacecraft (just that!) or in real combat situations (indeed it is probably better to look at your real opponent rather than your Battlefield game)...
However (and the however is important), these limitations no longer apply in the case, and only in the case, of an epidemic of a virus transmitted by bite or contact with bodily fluids, which would cause the reanimation of human bodies and an insatiable need to consume human blood, flesh, brains or tissue, and which would result in the fall of civilization as we know it.
Cheerful scenario! Let's hope Amazon doesn't get the scoop on a health-related news that the world will only find out too late... Anyway, who said that lawyers, especially those who write UGCs in small print, don't have a sense of humour ;)
