1up has an interesting piece looking at games that have withstood the test of time, aging gracefully where others have not. Titles discussed include the Korean powerhouse Starcraft, Nethack, and the Sim series. From the article: "It's hard to label which games are suitable for repeated lovin' and which are forgettable. One gamer's Halo is another gamer's Superman 64. But when it comes to firing up a favorite, some adventures hold the same appeal they did when they were released years ago -- and jumping in for the fortieth round is every bit as pleasurable as the first time."
