currently the games available are for me not big enough draws to justify forking out £700 for VR. the other aspsect as mentioned is space on the vive to make it a more immersive experience.
there are some games which i can see VR being a fantastic experience, mainly those where the player is in a static position within the game world. in a tank/aircraft/spaceship for example. which while i have elite its is about the only game i own that i can immediately see any merit for ahving it. and i cant spend that sort of money for 1 game or to find out if any of the other games in my collection that would work.
i really wish that Valve/HTC and the Rift has a lower price point. i understand the need to recover development costs etc but the price is not something many people can realistically drop on a piece of hardware. if the uptake of the hardware isnt enough i cant see game devs making games specifically for VR as the market wont be large enough to justify it.
