What's an old (>17-ish yr) game with great writing and gameplay mechanics that would still hold up by today's standards?

Just a patient gamer (like, really patient) who recognizes that players' standards for what is considered a "good" game has risen over time because of a variety of factors. I'm curious– what's an old game that, if published today, would be met with applause despite the technological limitations of its time? Any genre. Nostalgia aside. Graphics are irrelevant, but art direction is.
