I think every Nintendo system should launch with a 3D Mario game going forward, if not that then I'd say an open world 3D Pokemon RPG game.
If the NX is a unified platform then a huge 3D Pokemon game could be a great bridge title to run on both consoles.
It's hard to pick just one game though, because you'd assume that going with a unified architecture would basically mean Nintendo could have the same quantity of games that they'd have for both systems at launch, but they'd work on both consoles, so it's basically like doubling the launch library.
