When this betrayal topic comes up people always focus on Squaresoft and FF7, though they shouldn't. Nintendo must have seen what was coming long before Squaresoft moved out of their US headquarters in Redmond Washington (which was literally located right next to Nintendo's own US HQ). They had very close communications with each other back then and they both knew that their exclusive relationship was coming to an end with Squarsoft's new ambitions and the N64 cartridge limitations.
On the other hand Nintendo failed to get a game series on the N64 which was completely possible on cartridges and that was already multi-platform. That game was Street Fighter. Sales of SFII were huge back then, even in Japan where Street Fighter II:The World Warrior outsold Final Fantasy VI.
Street Fighter II: TWW SNES sales in Japan = 2.87 million
Final Fantasy VI SNES sales in Japan = 2.55 million
Street Fighter II was one of the best selling 3rd party games on the SNES, if not the best. Failing to put a single Street Fighter game on the N64 was one of the biggest blunders for Nintendo, and Capcom is especially at fault here too.
