Go only tracks your head and one hand with the controller in it. Sophisticated VR setups require you to stand and move around to be useful with the added danger of running into stuff. On the positive side, the VR you experience on this cheap device is very good.With GO, I can experience most everything in a comfy office chair that swivels around. The big graphics intensive VR games and platforms are probably not going to run on Go, and that is going to be a problem for the VR industry as a whole if Go becomes a thing. Expect only 2 to 3 hours per charge, or do what I do and get an extra long usb to micro usb cable and keep it connected. HD-VR pictures and videos look great, and most of the content available is in this category.
Epic Roller Coasters is the best of these, not only with the most interesting environments, but there is a physics game you can play where you must use a brake and accelerator to finish as quick as possible without crashing. – Once you get tired of making yourself dizzy with roller coasters, you can go to the other extreme with a fishing simulator.
For as cheap as 0, you can get a completely stand alone VR setup.
