Sesame Street: Counting Cafe is a Sega Genesis-only game based on the characters of Sesame Street, which is produced by the Children's Television Workshop (now known as Sesame Workshop). Players learn how to count numbers with Grover as he tries to count, climb, and jump while collecting food items for counting. Bert has a tendency to thrown an egg in the mass and alter the order.[15] The skills learned and developed in this game can be used for later childhood, adolescence, and eventually adulthood. North America was the only region in which the game was released; it uses the American English language.

Known as The Super Shinobi II in Japan, Shinobi III is regarded by many as the high point of the series. It introduced a much smoother, faster style of gameplay while keeping the series' familiar trademarks firmly intact. The game marked Musashi's last appearance in a Shinobi game until Shinobi was released in 2002 for the PlayStation 2. At least two known beta versions of Shinobi III are currently in circulation, featuring almost completely different levels from the final game.

688 Attack Sub is a submarine simulator game designed by John W. Ratcliff & Paul Grace, published in 1989 for DOS systems and 1990 for Amiga computers by Electronic Arts. A Sega Mega Drive version was also published. The player takes command of a US Los Angeles-class or Soviet Alfa class nuclear powered attack submarine and plays 10 missions ranging from into either Cold War scenarios or combat missions in a hypothetical global conflict. As modeled in the game, the American submarine has more sophisticated electronics and more weapons. The Soviet boat has fewer weapons but higher sustained speeds. 688 Attack Sub is known as an early classic of the genre. John W. Ratcliff followed it up by SSN-21 Seawolf later. This was one of the earliest games that allowed two players to play against each other over a modem (or null modem cable).
