We've heard a few times now that Square-Enix has some interest in bringing Final Fantasy XIV to the Switch. The opportunity came up once again to ask Square-Enix how that was going, and Final Fantasy XIV dev Naoki Yoshida had the following to say.
"I'd like to open it up to as many platforms as possible - we want to include as many players as possible. Not just Switch - even Xbox, if it's interested in this, we'd like to open it up. We'd like to have it on as much hardware as possible. Even though the hardware might be different, they will be playing in the same world - it has to have cross server function. That's something that's at the core of FF14, so we'd want to keep that as a policy.
We have no intention to divide the servers per platform - we're working with one big community. I'm interested in other platforms, of course - I hope those first parties change their policies or mindsets. I'm an MMORPG gamer - I'd love to play with many people globally, and we've been talking to those platforms about getting it on their hardware. Positive discussion is ongoing. It's not as if we're not doing anything - we are actually talking to them, and the platform holders are showing their attitude in a more positive way."
