Its kind of hard to believe considering its not a franchise owned by someone else. I mean, from the article it sounds like the contract was completed without being rushed and the purchaser wasn't disappointed about features in it that weren't missing.
There are a couple of silly titles out there. Final Fantasy VI being Final Fantasy III on SNES, Final Fantasy IV being Final Fantasy II on SNES, Seiken Densetsu 3 = Secret of Mana 2, and what about the Street Fighter II craze? Then there's the stupid renaming fans do, like Lands of Lore = Eye of the Beholder 3.
