How small are we talking about? My PC sits in a very small room, and yet I can use VR. It does not sit in the living room. Size of the room is less of a deal than obstacles. You may have to rearrange some furniture out of the way while you play. I have to move my desk chair out of the way if I'm not playing Elite. Usually you don't move all that much – but stuff has to be out of your arm's way. Most games only require you to be stationary. It's just more immersive if you can move a bit.
