is there a way to trade in fft?

No.

What did you mean by trading.Trade what to whom ?

i think he means to any games store. i think you'd be lucky to get even a buck for fft. it's not anywhere to close to the same level as a ff7 if that's what you were hoping.

or i suppose he could have meant trading it in to neoseeker, which also would be a no.

At one time a copy was worth quite a bit but that was before the remake /port came out.
He could put his copy on ebay and see what he was offered for it.

True, My local game store usually has one or two copys in, I have two myself. FF7 on the otherhand was never in, I had to order my copy of that online, cost 71 US Dollars.
