Maybe cool? I guess the first thing you do in a new vr game is check out your hands. Finger tracking is just a natural feature that was inevitably going to be adopted but I don't think we'll be seeing games taking advantage of it soon.
Full body tracking is kind of creepy looking still because so few people have it but I want it bad. Then again I would want it for vr chat which I will never have the time to fully enjoy by pretty much ignoring real life.
