I mean people who pay for them. Of course i would not.
What i mean is we all know it's gonna lag and if some people are willing to accept that to play old games then fine. If the cloud makes retail offline games lag here and there i highly doubt people will find this okay as it looks like you wont have any choice but to use it for some games like Watchdog (could be wrong). Right now the only game i know making use of the could is Forza 5 and i've not read any reviews proclaming it made the gameplay or the ai any better than Forza 4 or the gfx any better than Ryse or Killzone.
I'm not sure what your point is.
Forza 5 uses 'the cloud' to offload ai functions and leverage that to try a new method for improving ai overtime by incorporating real gamer driving habits.
I don't know if any reviews have said the ai is better, but I do know reviews have definitely mentioned it being different, some noticing right away that the ai was behaving more like other players and less scripted.
Why would the graphics be any different because of that feature?
Remember, 'the cloud' is not a good option for improving things like graphics thanks to the real time nature of that. Plus, its impossible for 'the cloud' to cause games to lag while they are being played offline. Offline means no internet, which means no connection to the cloud. If someone makes a game that must have an internet connection, it simply wont play at all.
