+1 on what's said;
There are many security issues; internet providers are already cutting on bandwidth (bringing monthly speed and volume limitations).
Seeing that,a night of playing could easily cost you a few gigabytes of network transit.
Second,there might be applications where you will want privacy,and not for everyone to see.
The extra cost of subscription is another thing, many users, including myself,did not play WOW because it costs a monthly subscription fee, and I am not prone of sharing my banking info with any company online.
Let alone, pay $50 per year, per game, where other games just cost the CD ($25),and rely on local free servers, if they do support multiplayer.
Plus, you can always play even when not having internet.
I also agree with the lag issue.
We do everything in our power, to shave off 5ms on our LCD monitors.
They now go downto 2 and 1ms, yet we will play games over internet which has a 105ms lag?
The games that would work, often older games, that easily can run in software render mode (does not need a powerful graphics card) will probably be playable.
I am not for this idea;instead, AMD would do better creating their motherboards to have a plug and playable GPU (just like a CPU) right next to the CPU on the mobo, with a few hundred of lanes.
That would void the need for PCIE, and separate graphics cards.
Just plug in a CPU, a GPU core, and some VRAM (like you plug in DDR ram).
I think that'd be a much better solution,if CPU/GPU on one die is not possible.
