Dragon Scroll (ドラゴンスクロール 甦りし魔竜, lit. "Magic Dragon Scroll Dragon Reborn") is a 1987 video game that was released exclusively in Japan for the Family Computer. The game is non-linear and operates almost like a sandbox game. Many video games helped to influence this video game, including The Legend of Zelda. A large video game world helps to define the complexity of the gameplay. However, most puzzles are impossible for non-Japanese speakers to solve, but a fan-made translation patch has been made available by King Mike Translations in 2008.

DuckTales (わんぱくダック夢冒険 Wanpaku Dakku Yume Bōken?, lit. "Naughty Ducks Dream Adventures") is an action platformer video game developed by Capcom and based on the Disney animated TV series of the same name. It was first released in North America for the Nintendo Entertainment System in 1989 and was later ported to the Game Boy in 1990. The story involves Scrooge McDuck traveling across the globe collecting treasure and outwitting his rival Flintheart Glomgold to become the world's richest duck. Produced by key personnel from the Mega Man series, DuckTales would go on to sell over a million copies worldwide on each system, becoming Capcom's best-selling title for both platforms. The game was praised for its tight control, unique and non-linear gameplay and bright presentation, and is often regarded as one of the best titles for the NES, appearing on numerous "Best of" lists. DuckTales was followed by a sequel, DuckTales 2, in 1993. A Remastered version of DuckTales developed by WayForward Technologies, featuring high resolution graphics and the original voice cast from the show, was released in 2013 for PC, Xbox 360, PlayStation 3, and Wii U.
