Three years earlier, Doom was released. It had 4 programmers.
Six years before that, Final Fantasy had 1 programmer.
If you stick around for the credits in a modern video game*, it's clear hundreds of people are involved.
With that last comment though, I was mainly referencing AAA games (e.g. Bioshock Infinite).

> Although Final Fantasy is one of the most popular video games on the NES, programming an RPG proved somewhat difficult for Nasir. According to Sakaguchi, "it was the first time he had programmed anything like an RPG". Gebelli did not fully understand what an RPG was and how the battle system for such a game should work. I believe that Final Fantasy may have suffered from so many bugs and glitches due to Gebelli's understanding of RPGs. Nevertheless, Final Fantasy is still a fantastic game and Gebelli did not cease to amaze. Players were in awe at the battle system that Nasir programmed; being able to use four characters at once, the turn-based combat, and especially the spells and their glorious 8-bit animations.
I don't remember there being "so many bugs" in FF. As far as I remember, it was the only released-in-America FF to have any real challenge.
Also, having played the game - wow, two engineers.
