So... time for your evening update of actual gaming on the Rift! Hooray!
I just played Ethan Carter for an hour and feel completely fine (45 minutes yesterday and I had to stop because I was feeling woozy) and here's why. I played it standing today. Now the game isn't completely designed for being played this way, and I'll touch on that, but it probably should be played this way.
If you haven't played Ethan Carter one of the things the game does is missing object puzzles. It does them in a fairly unique way. So early on you find a train that's lacking a crank to get it started. When you discover the crank is missing you get a swirling cloud of letters that come together to form the word of the missing item when you are looking in the direction of that item. Once you're looking in the right direction, you press A or whatever, and it shows you a vision of where that item is.
Except in VR it's more like you're just standing near the object. You can't move with the analogue stick in these visions but what you can do is physically walk around the rough area where that object is.
If you're playing standing you're going to lose track of where the camera was, so even though these objects will always be infront of you if you're facing the camera, you likely won't be. Hunting for these objects when you know they're going to be really close to you is fun. At times I've dropped down to my knees to search. Once you know where it was in that general area, you can look around to try and pick out landmarks to help you get there once you jump back to your previous location and can now move with the stick again.
So something I'm finding out, turning with an analogue stick is literally the worst. I've played Doom 3 and Half Life 2 on my DK1 and DK2 for upwards of 3 hours in my longest sessions without issue. With a mouse. And you can't use a mouse and keyboard with Ethan Carter or any of the other games I've tried so far.
There is an upside to this. I love that I can just put the headset on whenever I want and it launches right into home and with a pad or the remote I can select my game or what have you... but in Ethan Carter that stick turning wears on your pretty fast. Fortunately it has the comfort mode where you just warp from spot to spot which would work extremely well while standing, but it if you're still turning with the pad that won't help so much.
Also, when you first load the game it's blurry as all hell. You'd presume (wrongly) that this is because it's scaling from 80%. But that's not why. It's the FXAA. Honestly just turn that off, no matter what scaling you play at. Sure you get some shimmery artifacts on the foliage and what have you, but the number of lines where you'll see obvious stair stepping is really minimal and it's better to see aliased leaves than just a big flat smudge of green that you're left with with FXAA.
I don't normally hate on FXAA but in this game in VR? Kill it with fire. It will just make you think you haven't got the headset on properly.
But back to the game. I'm up to the third investigation now (and have done a bunch of side puzzles) and it's so close to being a perfect fit for VR. The beautiful environment and serene atmosphere that the game really invites you to study in detail... all work brilliantly outside of the nausea inducing controls.
If you play standing you're going to run into a couple of problems. Walking around doesn't move your character, so if you get too far away from where your character is stood, you'll start having trouble entering through doorways or whatever. Also, the pause menu is oriented to the camera position, so you'll often pause and just be staring at nothing until you look around and find that menu. Sometimes if you're too far away from where you really are it can be hard to get an object to highlight as selectable.
But none of those things counteract the much less nausea inducing gameplay you get by turning by physically turning around.
Or... drumroll... the sense of presence. Because yes. So far, this game has given me the most moments of presence of anything I've played (other than pinball... which... you know). I entered a mine not long ago... and could feel how close the walls were... and just stood there turning around and drinking it all in. Not seeing your hands... yes... definitely a bit of an immersion breaker... even in a game like this with very limited object interaction even having one hand to tie you to your physical body would help I think.
But I just stood with my hands clasped behind my back. The photogrammetry really helps. It's quite a thing.
Now I think I'll play more pinball and curse my lack of money.
If HTC isn't quick I'll cancel that too! 
Hanging on the PSVR though because the lineup is awesome -- reminds me of the Dreamcast in a weird way.
