does nintendo expect third parties to make, in essence, two games for a ecosystem they've historically abandoned?
Well, Square Enix are making two versions of Dragon Quest XI for 3DS. A full 3D version and a full sprite work version. And up to a certain point you can play both at once. But still, they're essentially two fully separate games.
l wonder if NX games will be similar? There will be the handheld game and the console game? Will Dragon Quest XI NX console version be a port of the PS4 version and the handheld game be a port of the 3DS version? But to do that you will need massive storage capacity for the cards. Also that would mean there would definitely be console and handheld exclusive games. But everyone would have the handheld and console already so they dont have to buy a new system.
I think the biggest problem with this, apart from storage, is that developers would program to the lowest common denominator which would mean NX would get more handheld or mobile like games than console level games and games where console versions are just higher resolution handheld or mobile games.
Either way this could massively backfire on Nintendo if the handheld versions are dumbed down mobile games, especially if there is a standard requirement for every game to have console and handheld versions.
