RPGSite: "That announcement and other things at E3 - FF15, Kingdom Hearts - makes FF14 the odd one out, missing from Microsoft consoles. Your predecessor, Tanaka-san, said that FF14 was skipping Xbox due to Microsoft's Xbox Live policies forbidding cross-platform play and servers, and you later told me you were working to get the game on as many platforms as possible. Where does that stand now - have you signed an exclusivity deal with Sony, or is it still just down to Microsoft's non-movement on their policies?"

Yoshida: "To answer your question straightforward: The policy has not changed on Microsoft's side. The main reason from our side is that I don't want the community to be divided; to be split into two or more. For example, one player might be on the PC version, another might be on the PS4 version, and I'm playing the Xbox version - but we're not able to join the same game servers. That is just... I just don't like the idea. I disagree agree with it. If it was a P2P or an MO, then it would be fine - but for FF14, if that frustration happens, maybe one of those players says 'OK, I will give up my PS4 character and start out for scratch, making a new account from scratch on another machine. I don't think that's fair. I really want the community to stick together and not be split into two or be divided because of that reason. That's one of the reasons that means that unless the policy chances, Xbox just doesn't make sense to us."

RPG Site: "This sounds like a real point of frustration."

Yoshida: "To be frankly honest with you, there are now so many mobile devices, smart phones, everything -- why would you ever just stick to one platform from the hardware aspect? Just -- make it open to everyone? That's my opinion."

RPG Site: "So if they adjusted their position, you'd like to do FF14 for Xbox platforms?"

Yoshida: "I would love for as many players as possible to enjoy the game worldwide, so from a business point of view it could make sense to have it on the Xbox platforms. But as I mentioned earlier, that would bring about the tragedy that somebody might have to give up their existing character. Then players might get frustrated, and then they ask us - 'Square Enix, can't you do something?' and then... yeah. Unless that happens, we can't really do anything."
