So, at a particular point in our current project the characters decide to pass an evening with one of those old standbys, the drinking game "I Never". Except without the drinking, because at least one character doesn't drink.
This is entertaining from a writing/character development perspective, since not only does it mean working out who has and hasn't done what in order to answer the questions, there's also the matter of things like: who already knows about what other characters have done? Who will intentionally ask things they already know the answer to in order to score points? Who will ask what they really want to know? And who will carefully avoid asking about things they don't want to know or don't want to make public?
Of course, in a hentai game, which this isn't, the questions would probably get a lot more explicit.
