A:Answer Both, actually. Most computer games will need to be installed on your PC, but he will be able to download and play most Android games without a PC.
Two things to note: 1. Storage is limited on this device, so add a USB drive if you plan on downloading lots of apps or games. 2) There are also services installed that give you access to PC games via cloud gaming. I'd recommend reading professional reviews (CNET, Engadget, etc.) for more info.
