Fries praised current head of Xbox, Phil Spencer for opening up Xbox Live for cross-platform play and called on Sony to respond.

He told IGN: "I think he's done a great job of fixing things - a great example is this recent thing, this opening up Xbox Live for cross-platform play.

"I hope that Sony is going to respond.

"Likewise, I'm a big fan of Shuhei Yoshida at Sony as well. He's been a great guy, loves games and it's good to see some of the war ramping down, more respect and cooperation between those two groups.

"So I'm very optimistic for the future of both companies."

Previously Microsoft announced plans to support Xbox-One-to-Windows-10 multiplayer, with the company saying: "First, in addition to natively supporting cross-platform play between Xbox One and Windows 10 games that use Xbox Live, we're enabling developers to support cross-network play as well.

"This means players on Xbox One and Windows 10 using Xbox Live will be able to play with players on different online multiplayer networks - including other console and PC networks.

"Of course, it's up to game developers to support this feature, and Xbox Live players will always have the option of choosing to play only with other Xbox Live players."
