While I'm a big fan of the Metal Gear Solid games, I was never a fan of the older games. I played the NES version first, and didn't get very far at all. I managed to play the true original game on MSX which was included in the enhanced version of Metal Gear Solid 3.
Now I can respect that some people can get into the game. It does have the same weapons, gameplay, and plot as it's big brother sequels.
However this picture is a good reason why I never lasted very long. It's really hard to hide from guards, and gun-fights are almost impossible to win if you get caught. Way too hard for my tastes.
