core loop

watch the resident's routine -> hunger, thirst, and mood drift -> deliver food, water, gifts, or pats -> type polite requests -> mood decides whether he complies -> repeat across sessions

design notes

Rich Gold conceived the game and David Crane built it at Activision; the documentation presents the little people as real beings living inside the computer, with the player as their caretaker. Each disk's serial number seeded the resident's name (from 256), shirt color, personality, and behavior, so every copy hosted a different person. There is no win condition: the resident cooks, reads, plays piano, phones, and types letters about his feelings on a day of about six real-time hours, and his mood gates whether typed requests are obeyed. The cassette C64 version dropped memory, letters, and card games, which shows which systems carried the sense of a persistent person.

Natural-language interaction

Typed requests such as 'Please play piano' are matched against a keyword vocabulary; politeness helps, and a sad or sick resident may refuse.

uses

Personality traits

Seeded personality and mood parameters change which activities he prefers, how often he invites the player to cards or writes letters, and how readily he obeys.
