The third Final Fantasy game was released for the Nintendo Famicom in Japan in 1990. It wasn’t officially translated into English until many years after its initial release, so a variety of fan translations exist online, and their quality varies wildly. The TransTeam translation I found to be pretty good although the font and text alignment isn’t perfect.
The very first ever Final Fantasy game was in Japanese only, released for the MSX in 1987. This 1990, NES remake of Final Fantasy was when Squaresoft really made the rest of the world first sit up and take notice.
