The Nintendo 64 (commonly abbreviated N64) was the third home video game console released by Nintendo. It was first released in Japan in June 1996 and was meant to compete against the Sony PlayStation and the Sega Saturn. The Nintendo 64 was Nintendo's first console made for 3D graphics. It uses plastic cartridges instead of CDs or disks, making load times faster. Because of this, the games cost more to make. The controller for the Nintendo 64 was shaped like an "M" and had 10 buttons and a joystick. Sony used the N64 joystick design to make their DualShock PlayStation controller. Out of the box, the Nintendo 64 had 4 MB of RAM, and it could be upgraded to 8 MB with the expansion pak.
