>how's the finger tracking with vive controllers vs cv1 controllers?
Rift tracks two fingers and a thumb, but it works out better than Index. Vive has nothing; you press directions on a trackpad in VRC to make hand gestures.
>I can't move anything else except for my head and hands in games, right? 
Not directly, but inverse kinematics predicts the rest of the body. If you move lower in real life, you will crouch in game, but it obviously won't be a 1:1 representation of your real body position.
