Stanford has a project going on "How They Got Game: The History and Culture of Interactive Simulations and Videogames."

It has come up with a list of the 10 most important games of all time:

The chronological list, submitted for review and potential permanent preservation to the U.S. Library of Congress: Spacewar (1962), Star Raiders (1979), Zork (1980), Tetris (1985), SimCity (1989), Super Mario Bros. 3 (1990), Civilization I/II (1991), Doom (1993), the Warcraft series (beginning 1994) and Sensible World of Soccer (1994).

Just think of the generations of happy wrangling that await us, akin to wars over the all-time all-stars of baseball or football.
