"Busted's" drug-themed subject matter allows it to play with campus-life tropes in a surreal manner, with a humorous effect. This also allows it to apply some of the more annoying conventions of old-time adventures, like hunger and sleep puzzles, to its collegiate setting in a relevant and clever way.
The result is as much a frivolous survey of university annoyances and practices as it is a homage to first-generation text-adventure games. It's enjoyable, engaging, and funny.
Play the AdvSys version if you're able to; it's much better implemented than the Z-Code version.
