Here's a short story:

The game pad controllers were more-or-less copied directly from the Game & Watch machines, although the Famicom design team originally wanted to use arcade-style joysticks, even taking apart ones from American game consoles to see how they worked. However, it was eventually decided that children might step on joysticks left on the floor and their durability was also questioned. Katsuyah Nakawaka attached a Game & Watch D-pad to the Famicom prototype and found that it was easy to use and had no discomfort. Ultimately though, they did install a 15-pin expansion port on the front of the console so that an arcade-style joystick could be used optionally. The controllers were hard-wired to the console with no connectors for cost reasons. 

At June 1985's Consumer Electronics Show (CES), Nintendo unveiled the American version of its Famicom. This is the system which would eventually be officially deployed as the Nintendo Entertainment System, or the colloquial "NES". Nintendo seeded these first systems to limited American test markets starting in New York City on October 18, 1985, following up with a full-fledged North American release of the console in February of the following year. Nintendo released 17 launch titles: 10-Yard Fight, Baseball, Clu Clu Land, Duck Hunt, Excitebike, Golf, Gyromite, Hogan’s Alley, Ice Climber, Kung Fu, Pinball, Soccer, Stack-Up, Tennis, Wild Gunman, Wrecking Crew, and Super Mario Bros.h[›] Some varieties of these launch games contained Famicom chips with an adapter inside the cartridge so they would play on North American consoles, which is why the title screen of Gyromite has the Famicom title "Robot Gyro" and the title screen of Stack-Up has the Famicom title "Robot Block".
