So, in the PlayStation version of the original Final Fantasy they replaced that one guy whose name I can't spell with Link. In an elf village where the elf sprites look similar to Link from the Zelda games.

This obviously means that the game's world and Hyrule are connected and the Zelda games are in fact prequels of the original Final Fantasy. There can be no other explanation!

Final Fantasy/Legend of Zelda crossover game, anyone?
