Nintendo World Cup wasn't a game developed by Nintendo. It was developed by Technos, and it was ported to PC Engine and Genesis in Japan. It's part of the Kunio-Kun games (like River City Ransom and Dodgeball). Its japanese name doesn't have the word Nintendo.
Since not many people will remember Nintendo World Cup, it's better to make a new football IP.
