However I have now read the piece called Gaming and Entailment and sounds about right, certainly I see little to argue with in what you've said. Ironically(?) enough it makes perfect sense, in fact, unless I'm missing the point somewhere it feels fairly uncontroversial - some may not like the choice of language and the negative implications that could be supposed to arise from it I guess but that's it.
Maybe I'm not getting it but, if I am, I think that you're saying, for example, that if you were at the dinner table with someone and you asked them to pass you the salt, then one way of describing that is as a move in a game that seeks to steer (or manipulate) them into moving the salt so you can use it. And no doubt some might say "I'm not manipulating anyone" but that would only be a sort of delicacy about their perceived connotations of the word manipulate.
