Kojima absolutely hates Metal Gear on NES, calls the title 'pitiful'

“I had absolutely no participation in the development of the NES version. The NES version was a pitiful title developed cheaply and simply by a small team in Tokyo. That was during the bubble economy where anything and everything that was released would sell. I came across the game in a bargain bin and tried play it, but the game design is pretty bad. There is some gameplay that includes infiltrating a base that didn’t exist in the original. However, even I, the developer of the original game, was unable to infiltrate the base even once.

Furthermore, being Metal Gear, it goes without saying that Metal Gear should make an appearance at the end. However, from what I’ve heard, due to the technically difficulties in displaying the sprite on the screen, they swapped Metal Gear out for a gigantic monitor. That made me see that whoever created the game had no sliver of appreciation for the players. However, even thought it was an abomination, it was during the bubble economy and it sold millions overseas. That title has only soiled my reputation.” - Hideo Kojima

Granted, it’s not the most faithful translation of Kojima’s work, but it’s definitely not the worst game ever. It helped to birth some interest for the series in the states, and is remembered quite fondly by long-time gamers. That has to be worth something!
