So, er, the funny thing about this is this article is a slice of a quote from a larger interview, and here's how the exchange about cross-play came about from the interviewer side (my side!):
"Is this a position that's changed over the course of the Xbox One's life cycle? I ask this as I remember the Final Fantasy 14 producer Naoki Yoshida specifically telling me in an interview that game didn't come to Xbox because of differences there that couldn't be reconciled at the time, when that game was new."
To this Ybarra says he doesn't know about that specific situation, but it's from this he then launches into his explanation that Nintendo and Valve are close by and they're willing to talk to anyone. He also says something along the lines of - consumer demand has changed, and the MS stance changes with that. My editor over there has been putting up these one-shot articles of parts of the interview over the past few days, but the full transcript of me and Mike chatting should be going online as a long-form read either tomorrow or Friday.
Though don't expect any more FF14 talk - that was it.
