A childhood belief about computer games

I started wondering how computer games actually worked at the age of nine. Having figured out that computer games are made up of series of images like movies, I'd ask my dad how the computer could have enough memory to store all the possible ball and paddle combinations in ARkanoid for the PC. having to remove the mouse driver for extra memory in games was a commonly needed and cryptic operation for a kid back then, though I had no idea what the numbers actually measured. Later on the very same year, I would wonder whether it's the car or the road that's moving in Geoff Grammonds World Circuit. Now, fifteen years later, I'm graduating in software engineering.
