'Leisure Suit Larry: Love for Sail' included some much more risqué elements compared to previous installments. It also featured more fleshed-out, cartoon style graphics than its predecessors, as well as full voice acting. The game also shipped with a "CyberSniff 2000", a sheet of numbered scratch-and-sniff paper, corresponding to a number displayed on the screen at a certain location, so that the player can get a scent of what the area the player character is in smells like.
