Defictionalization: Atlus's special edition of Catherine comes with (among other things) real life versions of a pizza box from the bar Vincent frequents, one of Vincent's shirts, and even a pair of the boxers Vincent wears in his nightmares.
No Export for You: Intentionally subverted. Atlus initially played at the North American fanbase by claiming that they had no plans to release the game outside Japan in a late February 2011 interview. After roughly a day of a raging fanbase, Atlus Faithful members received a cryptic e-mail in Catherine colors with the phrase "Do you still like us?". Whether the teasing was intended to continue or not is unknown, as GameStop accidentally leaked the official release date a few days later. Atlus finally confirmed it with an e-mail announcing the official site and the tagline "...Cat's out of the bag". Clearly they never intended to leave Catherine behind, but they were aware of the trope.
