Not sure if I share this sentiment, I read elsewhere Valve is treating this as their next "flagship" release, a true first class VR game (hopefully not just some 30 minute "experience" that ends right as it's getting good). It this were literally any other game studio I'd have an eyebrow raised right now, but when Valve puts their full muscle and creative energy behind something as a flagship, lead-off hitter, they've yet to disappoint.
Genuine question: when would you say is the last time they did that? I don't really think of Dota 2 or CS:GO or whatever to be "flagships." I'd have to go back to, Portal 2, I guess, but I'm not sure even that I would call a "flagship," just a really good game. Certainly the Orange Box as a whole... but that was 12 years ago. Even Portal 2 is 8 years ago.
At least, in my initial comment, that's the intention I had in mind.
The tracking is basically "finger open or closed" and even then it's not terribly accurate. It frequently won't pick up fingers next to each other correctly -- if I point at something with my index finger, it picks out the middle finger as extending as well (even if it didn't). The way they track the thumb movement in particular does not feel remotely natural; it feels like you have to press an awkwardly-placed "close thumb" button rather than just making a fist.
The Valve Index's finger tracking is a gimmick in its current implementation. I really don't think we'll be able to get accurate motor control without a glove.
