Don't kid yourself: data centers are easier to have closer to many locations, but ones with hardware that works for cloud gaming, less so. And even in a best case scenario, it's still too big a delay to comfortably play anything apart from casual games.

Even streaming a game from your PC to living room box, such as Nvidia Shield, even wired, makes it nigh impossible to play racing games well, or anything that requires aiming. It's not far, almost playable when streaming in LAN, but any WAN in the mix and it's just not feasible.

Networking has a long way to go before streamed reactive games are even close.
