As it has been pointed out, Nintendo is a scummy company. They at least used to repackage their old titles as new titles. They're straight up re-releasing old titles. For all the shame Nintendo fans used to give Sony for porting The Last of Us over (God of War 3 and Uncharted collection wasn't announced at that point), they sure seemed to have changed their tune. 90% of the Switch library being the Wii U library.
