My all time favorite game. A friend had a working NES system a few years back, and I raved about this game. I got it off Amazon and played it with them. I was not disappointed, and quickly fell back into the patterns, challenges, and fun times I had with this game as a child. I spent many nights playing this growing up, and I think that it is a skill to master a game as difficult as this one. It took me a long time to beat this game, and using the codes do not justify the work and satisfaction that comes along with the start to finish of Metroid. This game is awesome. Pick up an old copy and see. The new versions are pretty cool too, but none of them compare to this gem
