To add to this point - I personally only buy/play Room-Scale games for this reason. And with HTC expected to sell additional LightBox sensors, it's quite possible I'll be able to expand my play space from the current HTC Vive max of roughly 12x13 to pretty much fill my entire basement. Of course you are limited by the cabling right now but HTC has a wireless module already announced for release during the first half of this year.

Exciting times for VR after decades of false starts.
