Infocom has gone down in history as the best makers of text-based adventure games. Of all the games they ever made, this is potentially their best. Combining magical realism and the real-life experiments that resulted in the successful Trinity nuclear test in New Mexico in 1945, the game creates a biting statement on the futility of nuclear conflict and the inevitability of the heat death of the universe that you really can't fully appreciate until after you beat the game.

Good luck doing that without a guide though, because this game is hard. Really hard. But if you persevere, you'll have an early example of a video game story with real emotional weight and thematic plotting. It's exhibit A of games as an artform, and modern games could stand to learn from it.
