Henry Lowood, curator of the History of Science and Technology Collections at Stanford University, has announced a list (he's actually calling it a "canon," which is a particularly loaded term for a student of literature) of the "10 most important video games of all time."
Star Raiders (1979)
Super Mario Bros. 3 (1990)
Civilization I/II (1991)
Warcraft series (beginning 1994)
Sensible World of Soccer (1994)
