"Sometimes people wonder why the video game industry is so sequel-driven. It's not, really; it's IP-driven. Attaching your gameplay to a familiar logo with an informative number at the end makes it seem both familiar and yet new, engaging but easily enjoyed. That's why Namco Bandai released Soul Calibur 4 instead of Create Your Own Fighter Guest-Starring Darth Vader, why Square-Enix slaps Final Fantasy into every title it can, and why Far Cry 2 isn't called Open-World African FPS Adventure. You make the games feel "safer" that way."
