I don`t think i`ll be hearing from square. There are other games which put it right FINAL FANTASY and they got nothing.
Because somebody else has got away with it (thus far), doesn't somehow magically make it legal. Moreover this project is free and even if they contact me, I`ll just change it :)
I'm afraid that argument will hold little water if they find out and decide to sue you for loss of profits for the time it WAS called Final Phantasy. Because - as I'm sure you'll admit - your game looks nowhere near as good as the original Final Fantasy series and that could put people off buying those titles.That's the argument they'd use in court, and its a very strong one. Its highly likely they'd win, as well. In that case, you'd have to pay a vast amount of compensation. If you haven't got money, they'll take your belongings including your house and your car and anything else of any value. If your family has anything of value that you benefit from, that will go as well. So, bye-bye television set etc. You *could* end up bankrupt.
Change the name now - you're skating on very thin ice. It simply is not worth the risk.
