Ok,...still? TLOU has fantastic MP, as does uncharted, GT sport, owning both I still don't see much difference. Like I said i'd give MS the edge due to ears and Halo but they are comparable, Not close is hyperbole imo. MS definitely focuses on it more then sony though. I mean GT sport is one of their biggest franchises and it was an online only focuses title.
In what world is the multiplayer in TLOU or Uncharted even in the same universe as Gears or Halo. Crap on the redundancy of Gears/Halo all you want, but the Multi player in every sense except your personal option, better that TLOU and Uncharted....
I think Sony has a stated goal that they won't "displace" 3rd party games with their own things which now a days basically comes down to MP shooters.
As long as there is a healthy supply of games of a type from 3rd party they won't be making their own.
