I think the entire line of thinking that you need a first person perspective to be immersed in a game or virtual world is also flawed. As someone who has been on Second Life for more than 16 years now which uses neither VR equipment nor a first person camera 90% of the time I can certainly "feel like I am there" despite all of those factors and in the presence of many other factors that do not exist in RL like teleporting and camming through walls just fine.
