I agree that it would be pretty neat. I've been following the Rift for awhile now and I am so so excited to be able to use one. I do, however, feel like in order to truly get the most out of the Rift, you have to play games on it that have been developed with VR in mind from the start. So while it would be very interesting to use one for ESO, I just think it wouldn't be
as amazing as using it in a game that was built around VR during early development.
