Level-5, which has developed several titles for Square Enix, is working on a new multi-platform game called Time Travelers. Online in Japan, people are pointing out that the Time Travelers' logo "looks like Final Fantasy". While it's not a straight up knock off, there are certainly shades of Final Fantasy in it.
But, honestly, it's sometimes difficult to make a game in Japan without having shades of FF in it. It seems the same is true of logos.
