Look it up
it can and has been used in business
and I don't know for a fact that Nintendo uses it but it is likely
The information in said link outright stated they followed the book, but it certainly wasn't Nintendo, nor any business that is well known. Claiming that a thriving business like Nintendo would follow such an unorthodox method s of business is ridiculous. It's grasping at straws to try to tie it. It's as senseless as someone claiming that anyone who tries something followed the story of the little engine that could.
There is a difference between relying on, and using.
Strategy and stratagem in this old-ass manual of war might be considered basic nowadays, but no wise tactician in both battles of arms and battles of economics ever ignores the basics. Complexity allows for amazing accomplishment. Simplicity allows for amazing accomplishment if you've the wisdom to keep it simple.
Point bein', there ain't no particular evidence whether Ninty has or hasn't had their business practices and/or ethics influenced by the Art of War. The book has it's uses in reference to businesses large 'n small, and there is the possibility Ninty may of included it in their economic brainstorming sessions or other such things.
