Kotaku's Richard Eisenbeis says that "at times [he] literally forgot [he] was really sitting in my living room" while playing with the Oculus Rift—a new virtual reality gaming eyeglasses system—for five hours straight. He really means it. His description of the surreal experience is incredible.

When Alyx jumped into my arms at the start of the game, my hands jerked off my mouse and keyboard as I tried to catch her in real life. It really is that immersive.


It must feel surreal. The downside: a headache at the end of his 5-hour marathon. But anyone gets headaches after 5-hours of intense anything. Is this the future of entertainment?
