You guys have to stop ragging on the Atari 2600! The guy that made that system (Nolan Bushnell) also made Chuck E. Cheese! I'm dead serious! I saw it on a video game special that was called something like "Game On: The Unofficial History of Video Games!"
My favorite is the Nintendo 64 mostly because all of the great games it has like "Super Mario 64" (greatest game in the world) and Legend of Zelda: Ocirina of Time (best-selling game ever except for Super Mario Galaxy!)
