Nintendo has confirmed with VG247 that it supports cross-play between the 3DS, Wii U and non-Nintendo platforms, including other consoles.
Responding to a query about Pure Chess, which is likely to support cross-play with PlayStation 3 and Vita, Nintendo confirmed it's given the go-ahead.
"We can confirm that cross-platform functionality is possible in certain titles that play on Nintendo 3DS and Wii U, as well as other video game systems not made by Nintendo. We are committed to helping developers realise the full potential of their software on Nintendo systems," a representative said in a statement.
"We can confirm that Disney Infinity from Disney Interactive Studios, Cubeman 2 from Three Sprockets and Pure Chess from Ripstone, all have the ability to play on Nintendo systems while at the same time communicating with consumers using those same games on other systems. Additional games using this functionality are in development."
Cubemen 2 was the first game announced with cross-play, and if Sony agrees, Pure Chess will be the first to have cross-play with a rival console - as opposed to mobile or computer platform. Disney Infinity has cross-play with mobile apps.
