"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.
This game channels the player towards a pivotal, brilliant, "gestalt" puzzle which requires the player to piece together a couple of different patterns that the narrative created through its repetition of the backstory. The fact that the puzzle works so well is impressive all by itself, but "Spider and Web" also features clipped, stylish prose that creates a tense, claustrophobic atmosphere and describes a sinister, memorable NPC.
"The Plant" is an engaging game which plays off the silliness of high-tech conspiracy theories by whimsically contrasting current technology with that of a former, fictional, Eastern-Bloc country.
Players learn about this conspiracy by solving mostly-innocuous, but frequently amusing, puzzles in each of the three areas of the game, but each area also contains a challenging and ingenious puzzle which provides access to the next area of the game. The puzzles are well-implemented, but each area contains a non-interactive scene which changes the game-state to allow the set-piece puzzle to be solved, and one of these scenes isn't well-clued and could be easily missed.
Nevertheless, "The Plant" is an excellent text-adventure game, which is well-worth a player's time.
