# 1981 in video games

"none" is preferred when the title is sufficiently descriptive; see [[WP:SDNONE]]
Fueled by the previous year's release of the colorful and appealing Pac-Man, the audience for arcade video games in 1981 became much wider. Pac-Man influenced maze games began appearing in arcades and on home systems. Pac-Man was the highest grossing video game for the second year in a row. Nintendo's Donkey Kong defined the platform game genre, while Konami's Scramble established scrolling shooters. The lesser known Jump Bug combined the two concepts into both the first scrolling platform game and the first platform shooter. Other arcade hits released in 1981 include Defender, Frogger, and the Galaxian sequel Galaga.
On the Apple II, Ultima I and Wizardry: Proving Grounds of the Mad Overlord each kicked off a long running role-playing game series. Atari's VCS port of Asteroids was a major hit with the console. The best selling home system around the globe was Nintendo's Game & Watch for the second year in a row.
