Ridiculous. No, you're looking for a boobie magazine, hentai or regular porn. Games are *all* about interaction, whether they're more immediate, action or simulation oriented, or whether it's about decision making and meaningful choices (i.e. a plot that is in the hands of the player), or both or something inbetween is another question, and both is fine, since they're exploiting exactly what games add on top of all the other media.
This, let's call it the degree of freedom, is an easily measurable and objective attribute to classify what's a game, and what is not (e.g. a VN with a branch or two is barely a game and as such a failure in design and spirit of games). But hey, feel free to present a better way of classification that holds up.
And really, the art of this would deserve a proper game, or can't we even agree on that? Do you even play any game at all, or just go ahead an pull out the CGs? lol. As initially said: ridiculous.
