GRTV had a chat with Mediatonic's Luke Borrett about the pidgeon dating simulation that is Hatoful Boyfriend.
"It's very immersed in Japanese culture. If you know like the Persona games and 999... visual novels style gameplay. It's taking that and all the anime tropes, and dating sim tropes you'd ever know. And sort of mixing them up in a parody, but also doing its own serious story about why you are the only human at St. Pidgeonations High School and why you are dating birds."
