Hideo Kojima has revealed that he only got a chance to make his cult vampire RPG Boktai: The Sun is in Your Hand because he took advantage of a completely different Konami project.
Speaking at the Sydney Film Festival, Kojima explained how he's always looking for technological improvements that might be useful in the future - a habit that stretches all the way back to the early 2000s. That's when he made Boktai: The Sun is in Your Hand, a vampire fighting RPG that's developed a cult following thanks to its central conceit - a UV sensor embedded in the cartridge that made your weapons more powerful when they were charged by real sunlight.
