This is for a novel: should the title of a non-existent video game be italicized when it's spoken as a solecism by a character?
Example: the mother tells the kids to stop playing Immortal Kombat. The kid replies that it's Mortal Kombat. For some reason this seemed incongruous, or just plain misleading. I thought of not italicizing Mortal Kombat as well, so that they match, as it is spoken in dialogue. I understand the rule is consistency, but more spoonerisms or malapropisms may be spoken later in the novel--which is somewhat rich in pop-culture references--so I'd like to know now.
I suppose the main reason that it seems weird NOT being italicized, is that I am so consistent in the first hundred pages with titles, so that any careful reader or knowledgeable consumer of pop-culture will see Immortal Kombat and immediately understood that the mother misspoke, which is what I really don't want. I want that second of hanging, that second of a reader asking him- or herself, "Huh? Is that a game?"
