30 years? Wow... talk about a nostalgia trip!
My older cousin had one and I had seen him play it, and I had played on an Atari 2600 and Atari 7800 another relative had. I got my first NES for Christmas, 1990. I had just turned 7 yrs old and I still remember opening it up, seeing the packaging on the side with the Zapper and SMB/Duck Hunt combo. (I never saw the ROB unit). My mother had recently quit working at the local mill to take care of myself, my little brother, and little sister, and my dad was a truck driver, so our financial means were limited and I'm still amazed and ever thankful they bought me a Nintendo for Christmas.
We hooked it up that morning to a TV my parents bought earlier in the 80s from a large furniture and home furnishings outlet near Spartanburg. It was one of those old, very large TVs, that sat in a wooden cabinet and looked like a piece of furniture. Me and my mom worked on getting through level 1-1 all morning long, when we finally went into level 1-2 I was amazed that the game was more than one level!

It is actually kind of a shock I grew to love the NES though, because after getting the system the follow up games I ended up getting from friends and relatives over the years were such gems as Circus Caper, Super Pitfall, Back to the Future, Ghostbusters, and Top Gun - not what I would call a stellar line up to show off the system! I ended up playing through a lot of my cousin's games: SMB 2 and 3, Ducktales, Dragon Warrior IV, Zelda, Mega Man 2, and Destiny of an Emperor.... Those game all left a big impression on me. After he got a SNES, I picked most of his old NES games and kept playing them all through the 1990s.
Ah, the memories!
