Gamers who live in/near New York City or plan to visit my lovely stomping grounds at any time around or after March 2013: you're gonna want to check out MoMA. New York's Museum of Modern Art will open the doors on a permanent video games exhibition in the museum's Philip Johnson Galleries starting in March 2013.
The exhibition will highlight 14 games to start with, though the wish list apparently includes a total of 40 titles to (hopefully) be added "over the next few years." It seems that MoMA intends to shine a spotlight on game design, with highlighted games being included for more than just their "visual quality and aesthetic experience." The starting 14 is a pretty scattered representation, but a good one, I think; Pac-Man and Tetris of course, but also EVE Online, Myst, Dwarf Fortress, and Canabalt (among others).
Take a peek at MoMA's website for a rundown of the 14 games and a mission statement that lays out the goal of the exhibition.
