There are two genres which work perfectly with the Oculus Rift: first person shooters and space sims. Seeing as Star Citizen is essentially a mix of both of these (as well as having a third person option), any lucky owners of the virtual reality device will find it the perfect accompaniment to the game.
Using the oculus while flying around in a dogfight will allow every Star Wars fan to live out their spaceship piloting fantasy. No longer will you be frantically inspecting a radar and trying to work out where that incoming fire is originating from, now you can simply turn you head and look out the windows, just like Vader would.
Utilizing the rift in sections that take place outside the cockpit will have its advantages as well. Not only will it make the first-person shooter element a more immersive experience, but even mundane tasks such as walking around the hanger and taking items from your locker will have that ‘I’m really there’ feel to it.
