The Galaga series (including Galaxian) was essentially the next logical step after Space Invaders hit the scene. The enemies were now individualized and agile and this made a world of difference. Galaga is the link between the pioneering concept of Space Invaders and modern shmups. In a way, Galaga is to Ikaruga as Pac-Man is to Metal Gear. (Think about it. In a way, Pac-Man was one of the first stealth games!) Galaga is when the shmup genre had found its distillation, it was an archetype for many."
