Yeah it's VII, VIII and IX that are a pain in the ass. I don't know how I managed to get my mum FFIX brand new, it was so lucky that day I just saw it and got a preowned copy of FFVIII at the same time (which my mum bought off me just so she could say she owned all the FF games
)
I'll keep an eye out at my local shops for any games people want, we should make a thread where people state what they are missing.
