NoJ has been pretty good about training their next generation of talent actually. Splatoon was an idea that originated from their newer staff. Most of the recent Mario and Zelda games have been using more ideas from Koizumi than Aonuma or Miyamoto. In fact, Miyamoto basically doesn't do anything in the game side of the company anymore other than advising, so he's practically retired but cant really even hint at retiring without tanking the stock price.
This reminds me of the one time Seth Mcfarlane was based and actuallly had Quagmire call out Brian(often seen as Seth's self insert) for exactly this.

There were a bunch of lawsuits on Karl and also some on Twin Galaxies, in which Karl was involved in the lawsuits somehow. The arcade cabinet was the Twin Galaxies lawsuit IIRC. Billy has been suing everyone for years so its hard to keep track of them all.
No standing.
