Well now. The original Arkanoid was (and far more blatantly than Space Invaders) inspired by the original Breakout, only in this case the difference was - to put it charitably - "subtle". That's not to say that the things that Arkanoid added aren't appreciable - moving enemies, power-ups and even bosses were all added to the original design to spice up what was otherwise a clone - but the series hasn't stuck in our minds the way Space Invaders has. 2/10
