Yes, Nintendo wouldn't care, so much that for NES they forbade any company that developed to their system to develop to other system. And during SNES if a game launched on it them it couldn't launch anywhere else. Those evil SE and Sony backstabbing angel Nintendo.
Ill argue that quality needed control and that's because of Nintendo saving the industry from falling under. Harsh actions needed to be done. Damn Nintendo for taking hard action on a very corrupted industry back than.
