This game is beautiful and I fear that some of the beauty is lost on players who run from objective A to objective B without stopping to look at the scenery in between.
Other than trying it once I'd wager that nobody plays in first person mode.
When I actually tried it, I was amazed at the beauty I had been missing. My first thought was that I could easily greet lost in this game (in a good way) if I were playing with an Oculus Rift.

I've seen the suggestion pop up a few times in beta when the Rift was in the news as lot more with the disappointing response that there were no plans for support.
That had me thinking just how much support would be needed. I'm certainly no developer nor programmer but it seems to me as easy as adding a second player camera point. I'm certain there is a lot more than that.

But my point is, I'd like to readdress Oculus Rift support.
Without software, hardware will fail. This hardware is the future of gaming.
The first MMO with native Oc Rift support would be HUGE.
