Yes. Because Nintendo doesn't have a history of lawsuits.
Clearly you know little about your beloved Ninny. Back in NES/SNES days they were the Suing Trolls. They even stole the patent for Tetris, never paid a penny for the game that wasn't even developed by them, but by a guy who unfortunatelly lived in Soviet Russia, so he couldn't really claim Tetris as "private intellectual property". Not only that, they nuked the release of his game for the NES to remain the sole Tetris supplier for their hardware. The game was ready and already in distribution and WHAM, they confiscate and destroy all carts, all in the name of law and order. They stole the Wiimotes too - a nearly exact same controller was being developed for the Sega Dreamcast. I could go on, but what for? You do that yourself.
Your lack of infortmation amuses me. Every corporation is the same, every corporation is full of dicks.
