Pacific Novelty was a developer of coin-operated arcade video games. "Deep Death" was their first title, which was later licensed by Game Plan and re-released as "Shark attack" (1981). "Thief", a "Pac-Man" styled maze chase, was their greatest success.
"Thief" was licensed by Game Plan.
"Thief" was one of the games made by Pacific Novelty but it is not know who licensed the game. It may or may not of been Game Plan, who licensed "Deep Death", another game made by Pacific Novelty.
