Adventure game
An adventure game is a video game in which the player assumes the role of a protagonist in an interactive story driven by exploration and puzzle-solving. The genre's focus on story allows it to draw heavily from other narrative-based media, literature and film, encompassing a wide variety of literary genres. Many adventure games (text and graphic) are designed for a single player, since this emphasis on story and character makes multi-player design difficult. "Colossal Cave Adventure" is identified as the first such adventure game, first released in 1976, while other notable adventure game series include "Zork", "King's Quest", "The Secret of Monkey Island", and "Myst".
PlayStation
The original PlayStation, released in Japan on December 3, , was the first of the ubiquitous PlayStation series of console and hand-held game devices. It has included successor consoles and upgrades including the Net Yaroze (a special black PlayStation with tools and instructions to program PlayStation games and applications), "PS one" (a smaller version of the original) and the PocketStation (a handheld which enhances PlayStation games and also acts as a memory card). It was part of the fifth generation of video game consoles competing against the Sega Saturn and the Nintendo 64. By December 2003, the PlayStation and PS one had shipped a combined total of 102.49 million units, eventually becoming the first video game console to sell 120 million units.
