"We are very proud to announce that MoMA has acquired a selection of 14 video games, the seedbed for an initial wish list of about 40 to be acquired in the near future, as well as for a new category of artworks in MoMA’s collection that we hope will grow in the future. This initial group, which we will install for your delight in the Museum’s Philip Johnson Galleries in March 2013, features:
• Pac-Man (1980)
• Tetris (1984)
• Another World (1991)
• Myst (1993)
• SimCity 2000 (1994)
• vib-ribbon (1999)
• The Sims (2000)
• Katamari Damacy (2004)
• EVE Online (2003)
• Dwarf Fortress (2006)
• Portal (2007)
• flOw (2006)
• Passage (2008)
• Canabalt (2009)


In addition:

Over the next few years, we would like to complete this initial selection with Spacewar! (1962), an assortment of games for the Magnavox Odyssey console (1972), Pong (1972), Snake (originally designed in the 1970s; Nokia phone version dates from 1997), Space Invaders (1978), Asteroids (1979), Zork (1979), Tempest (1981), Donkey Kong (1981), Yars’ Revenge (1982), M.U.L.E. (1983), Core War (1984), Marble Madness (1984), Super Mario Bros. (1985), The Legend of Zelda (1986), NetHack (1987), Street Fighter II (1991), Chrono Trigger (1995), Super Mario 64 (1996), Grim Fandango (1998), Animal Crossing (2001), and Minecraft (2011).

How about that? The people over at the Museum of Modern Art consider our own humble man Chrono to be art. How's that for some recognition?
