I started gaming on a 2600, too, but I still find Metroid too primitive to enjoy. I would probably like it if I had played it when it was new. I remember being with a couple of kids at school who were talking about it while one drew the other a map from memory. I looked at the map and saw the interconnected horizontal and vertical passages, and then the foreboding note "Metroids!" above one cavern, which struck me like "Here be dragons" on an ancient map of the world. It was a mind-expanding experience just being confronted with that on notebook paper. And yet I didn't get to play the original until years later. I played Metroid II first, and Super Metroid, and it was longer still before I played the original. By then it had nothing left to grab me with.
