13.5 million Wii U’s have been sold, compared to 65 million Switches. That means that for more than 50 million people, the Wii U ports are new games.
In addition, you also have the fact that ports are often made by small, new or sister studios, so the main studio can just keep making new games and a port, remake or remaster does not have a negative impact on the development of a new game.
Ports, remakes and remasters also provide a more stable flow of “new” games.
Finally, you don’t have to buy them.
