Phantasy Star Online 2 will eventually make its way to other platforms in the West.
The reveal trailer only listed PC, and Xbox One as launch platforms, but head of Xbox Phil Spencer has since confirmed it's not an exclusive. Speaking to Giant Bomb at E3, Spencer told the story of how the deal came to be.
"Sega is primarily - ultimately responsible for it," said Spencer.
"I go to Japan fairly often now. I meet with all the publishers, and I go to see Sega - and I am sure they've been getting this from other places - and I just said, 'you know, so many of the constructs in today's multiplayer games [...] were born in Phantasy Star and 90% of the gamers today don't know what a Phantasy Star Online is.'"
After speaking to the Phantasy Star team, Spencer asked if Microsoft could support them in any way. "It was really just, I wanna do something with Sega. They were very receptive," recalled Spencer.
"I happen to have a soft spot for PSO and I do think it can be a meaningful franchise. [...] It was so cool to have them on our stage and to be able to work with them - and yes, it'll end up on all platforms," he added.

Phantasy Star Online 2 launches sometime next spring for PC, and Xbox One. It was recently confirmed that the initial launch is only planned for North America.
