ooohhh I See...
There are two different FF3s. One is the NES (and soon WSC) tiltle, only released in Japan. the other is FF3 on the SNES, only released in the USA.

The reasoning behind this is that the USA only recieved FF1 FF4 and FF6 which were named FF1 FF2 and FF3 to make it seem they weren't getting a raw deal... All this came to light when FF7 hit the streets and people started to wonder where 4-6 had gone, in truth it was really FF2-3 and FF5 they missed.

Anyway, your European right? you're gonna have trouble getting anything before FF6 on a console, because we never got any Final Fantasy before FF7... which means you're gonna have trouble locating FF4 anyway; i'm yet to find a ROM of FF4 that has a decent-ish translation, but "FF2" is a far-far easier version of FF4 than the one available in the US.
However Square-Europe are going to be making an announcement on the release of FF4 and FF5 in Europe soon

As a summary, this is a table showing Jap : USA releases...
