Why doesn't Nintendo make more games for it's systems?

[forethought14]

Based on Iwata's statements, with their unified environment for NX games should come out much faster. However, this doesn't mean that they will make all games run on any peace of hardware, this simply means that they would be able to push out games much quicker. Super Mario 3D World and Captain Toad are good examples of this used in a different way: let's pretend Wii U didn't exist, if they created Super Mario 3D World to run on the NX console, they could have used that same engine and assets for Captain Toad on the NX Handheld. Same engine, assets, different games, and on different systems. Let's say they create an engine for Super Mario Universe NX, they can use that same engine, assets, models etc to create Super Mario 3D Whatever on the handheld, then Super Mario Galaxy 3 for the console, Captain Toad 2 for the console, then Corporal Yoshi on the handheld and then Commander Toadsworth for another handheld game. I don't believe they'll use the EXACT same models and textures for each game, there will be too many similar-looking games, so they could simply modify already existing models, physics, assets etc to suit their different art styles to make them look different. They'll also have different engines that are each better suited to certain types of genres, and they can use those engines and assets over and over again, with modifications of course, you need to make them look different

They may also make a more realistic engine for lets say Metroid Prime IV, and use that same engine with similar assets for a 2D Metroid on the handheld, or some other realistic series. Of course, they could even create all-new games that aren't from their flagship franchises with those same assets. Splat2on could use upgraded versions of Splatoon 1's models, and they can even create an Octoling-toon game as a spinoff using the same assets. No more starting things from scratch if they don't have to, and those assets will be movable across the handheld and console. Before Iwata's passing, he stated that this could be done regardless of performance of each system, meaning that differences in raw power won't be an issue. I'd say NX is a very interesting proposition, they're setting themselves up for potentially having their most varied platform ever. They'll be able to make more games much faster. Hopefully they don't screw it up.
