Well I personally like Final Fantasy Legacy, it is the closest to the Final Fantasy gameplay than all of them. Though I think another Final Fantasy game is on there (not listed) trying to imitate the NES Final Fantasy 3 with similar smooth gameplay. But I haven't tried it personally. It's called Final Fantasy Legend of the Crystals. It was made by the user Dphoenix7 but it appears it's not hosted often and probably not finished. The media previews isn't too bad though.
