Knytt Underground developer Ripstone said in an interview with Eurogamer that Nintendo will allow cross-platform play functionality for its upcoming title, Pure Chess, which will launch on Wii U, 3DS, iOS and Android devices.
According to Ripstone creative director Phil Gaskell, Nintendo — which has traditionally had a closed platform — agreed to allow cross-platform multiplayer in the chess title, which means someone playing on the Wii U can compete with a player on a different console.
"...They said, 'Yep, no problem. You can have other console players playing against Wii U players. You can have smartphone players play against them. No problem,'" Gaskell told Eurogamer. "We're still talking to Sony about them relaxing their policies, but we don't think they'll have any issue with it. So when we launch Pure Chess, you'll be able to play against Wii U, 3DS, iOS and Android players. And when we patch PlayStation, those consoles will be added to the mix as well."
Polygon reached out to Nintendo for comment, but the company had no further information to give on the topic.
