Leisure Suit Larry III: Passionate Patti in Pursuit of the Pulsating Pectorals is the third entry in the Leisure Suit Larry series of graphical adventure games published by Sierra Entertainment. It was developed for multiple platforms including DOS, Atari ST and Amiga. The game utilizes Sierra's Sierra's Creative Interpreter (SCI0), resulting in a graphic style similar to its immediate predecessor, as well as a larger repertoire of MIDI music.
Some consider this game to be a return to form, as it abandons the linear progression of Leisure Suit Larry Goes Looking for Love (in Several Wrong Places) in favor of the dating sim aspects of the original title. The plot follows series protagonist Larry Laffer, fresh from an abrupt divorce, as he combs through a tropical resort looking for love.
The game takes place on Nontoonyt Island, the tropical setting from the previous game which has since been transformed into a resort. Like the city setting of Leisure Suit Larry in the Land of the Lounge Lizards, the island has several areas and is fully-explorable at the game's start. The controls feature a mouse-based interface and a text parser for directing the Larry's actions.
Littered throughout the resort are Larry's potential mates; whenever the player interacts with these women, they are featured in a close-up portrait, once again echoing earlier games in the series. The basic structure of the game involves Larry presenting each woman with gifts, although none of these items require money to obtain, unlike in the original Leisure Suit Larry.
Leisure Suit Larry III features a second playable character, the titular "Passionate Patti", whom the player briefly assumes control over. Patti's portion of the game is much the same as Larry's, including multiple 'death' scenes and a detailed character portrait of her love interest, a male stripper. However, the Patti sequences are more reminiscent of traditional adventure games, requiring players to navigate through a maze, as well as collect items for use in later puzzles.
