A Leisure Suit Larry 4 was once in production. According to Al Lowe, the game was meant to be the first multiplayer online adventure game, and was going to use a new way to play the game. However, there were many problems with the technology they had at the time, so the game was shelved. The ending to Leisure Suit Larry 3 was also very definite and had almost no way to lead to another game. Because of both of these reasons, the developers decided to skip 4 and go straight to 5 to be able to do what ever they wanted with it. The 4th game is now considered an in-joke among fans and developers.
