Gcreator of Game Maker's Toolkit testWhat Pac-Man Brought to Game Design | Design IconsSpace Invaders began as a Breakout riff, grossed over $3 billion by 1982 and spawned six clones in 1979 alone. Shoot 'em ups led the charts for eight years, about 40 percent of 1981's top 200. Its speed-up as sprites vanish created a spiky difficulty curve. Lesson: pick a mechanic with room for variation, and shape difficulty with relief points, as Pac-Man later widened the audience by changing theme.
From Space Invaders page notes, citing Mark Brown
Space Invaders started a genre because its mechanic invited variation. It began as a Breakout riff and grossed over $3 billion by 1982. Six clones appeared in 1979 alone, and it started the shoot 'em up, which was the top genre for eight years from 1979 to 1986.
Shoot 'em ups were about 40 percent of the top 200 games in 1981. Block breakers and snake games stayed fads, while the shoot 'em up branched into new scrolling, perspectives, rail shooting and bullet hell. Mark Brown: "the shoot 'em up was much more versatile."
Its speed-up as aliens die created a spiky difficulty curve. Aliens speed up as you kill them because the processor has fewer sprites to draw. Each new level also starts them lower on screen.
Together these make difficulty rise steadily and then ease at each new level, giving tension and a moment to breathe. Brown calls it arguably the first game with a modern difficulty curve: "This undulating staircase provides rising tension."
Its shooter formula shaped the arcade that Pac-Man pushed against. Rivals copied Space Invaders, while Iwatani built Pac-Man around eating. He saw arcades full of violent war and space shooter games that mostly attracted men, and aimed Pac-Man at women and couples with cute, non-violent design.
Space Invaders' invaders only side-step, and its UFO inspired Pac-Man's bonus fruit. A cited book puts Pac-Man's audience at 60 percent female.

Enemies speed up as you kill them because the processor has fewer sprites to draw, and each level starts them lower. This gives a spiky difficulty curve with relief at each new level.
