An opinion piece on Gamasutra looks into the common perception that a first-person view provides a much more immersive experience in shooters. The author argues that this concept needs to be reconsidered, as immersion nowadays is more dependent on what you see, rather than how you see it. The question is further complicated by ever-improving technology and new control schemes.
"It's important to realize that making a first-person game almost necessarily means making a game for the dedicated gamer. Innovations on the interface side could help lower the casual block, perhaps through the Wii, Project Natal, or the PS3's new motion controller. Regardless, it will take a lot of work and concerted effort to penetrate the casual audience with a first-person camera. The question is whether we even need to, when there are so many camera systems that games have yet to fully explore."
