Galaga pales in comparison to centipede. The bugs were faster, the shooting was faster and the mushrooms. . . yeah. you could shoot those things.

Galaga let's you get two shots off while the enemy barrages you. Centipede allowed you to shoot all you wanted but the enemies swarmed you like nothing else. Ah, the good old days of shooters. Now I can relive those arcade days. . . for a price.
