Sensors look slick. Set em on a shelf or buy wall mounts. They are wired and actually require usb 3.0 slots. 3 of em. 2 for sensors 1 for headset. More if you want to add another rear sensor but that's an upgrade. It isn't required to enjoy. For room scale games at least 6ft by 6ft??? For games that you sit down and maybe lean around or move your arms you can get away with 4x4
