If Shigeru Miyamoto dies... should Nintendo stop making Mario & Zelda games?

I'll miss that "Miyamoto touch" but Zelda is already in the hands of Eiji Aonuma. Aonuma was selected by Miyamoto himself to take care of that series.

In regards to Super Mario, don't forget that Miyamoto had Takashi Tesuka directing and producing most if not all the Mario games, including Zelda.

So those franchises could still continue being good for a long time.

At this point, with how long each character has been around, they have embedded themselves in video game culture forever. Many people know what to expect from these games and they can be recreated accordingly. Mario and Link rock :D

When Dr. Suess died did they stop making his books? The answer is no. Someone will always continue it.

the person who created samus died a long time ago, and yet they are still making metroid games

NO. I WILL CONTINUE THE SERIES!!!!!!!!!!!!!!!!!!!!!!!!!!THEYLL BE GREAT LIKE OCARINA OF TIME. of course. the series makes alot of money. hopefully the person will make them like the classics
