Super Mario Bros., I think. I know it's the first video game I got for Christmas (I also got the NES bundle that came with SMB/Duck Hunt).
I also remember playing Ms. Pac-Man and Donkey Kong Jr. at truck stops when I would go with my dad on his landscaping trips. But, I was probably older then since I don't think he would have taken a 7 year old to truck stops with him. I also remember playing a sitdown cocktail version of Millipede in the lobby of our local Pizza Hut. But I think that came after I got an NES for Christmas too since I remember joysticks feeling foreign to me since I was used to the gamepad. So, yeah, probably Super Mario Bros.
