Yep, the more the merrier with the Rift IMO.
I've had one for a few weeks now and I have to say I'm a total believer that this thing is the future of gaming.
Sure, you look stupid with it on. Sure, you're completely cutting yourself off from the outside world and neglecting anyone around you who might be in it. Sure, you have to reach for the goggles everytime you boot up a game or demo and try not to tangle your Rift/controller/headphones cords. Sure, VR sickness is still a problem that takes a little while for most people to get through.
But the experience on the inside throws those issues right out the window. Every person I've demo'd on the rift has at least said "WOW" or "Holy Shit" in those first couple moments. It's just too damn cool, and works too damn well. When you have it strapped to your head and you start looking around your favorite game world you'll understand. It's so responsive. The 3D is so tasty. Everything is life-sized around you. It's really incredible.
The catalogue of free demos alone has blown my mind multiple times. Just yesterday I was playing this 2.5D platformer prototype called Super Mega Mega. You control your character up and down and across platformer levels just like any other platformer ever. But the game world is a giant cylinder design, with you (the camera) positioned in the middle. As you're platforming along you have free look to look up and around at the level ahead of you, trying to find the best route to the top. It also has multiple depths for paths, allowing the character to jump from far paths to closer paths and vice versa, which looks amazing with the 3D.
This isn't a FPS, and it works spendidly. Will it cover every type of platfofrmer ever made? Maybe not. But I'm starting to think more and more that every genre/type of game will work not only "fine" with the Rift, but can be even BETTER with the Rift, we just don't quite know exactly how yet. But that's for developers to discover and figure out. It's truly exciting. A new frontier for gaming.
