My favorite thing about growing up with a Nintendo 64 were all the different controller colors there were to choose from. Each member of my family got their favorite color and used it exclusively during our nightly rounds of Mario Kart 64. There was red for me, black for mom, green for the older sister, blue for the little sister, and my stepfather was content with the original gray. We even picked up a spare translucent green along the way for guests to use. It may seem a little silly, but each of us grew really attached to our color, deeming them good luck to their rightful owner and a curse upon anyone else who picked them up. It was a nice little extra to our family gaming time.
Now that you know what they look like, which one do you want to go for? I'm really liking the red myself, since, well, I have quite a history winning games with a red controller between my hands. And once I have it, no one else can touch it. No one!
