I watched the video and thought "I would have liked FF13 if it was 16 bit." Nostalgia is powerful. As FF13 currently exists, I never finished because I bored half way through and put it down.

But, the truth is that they have made some 16 bit games. Final Fantasy Dimensions for iOS was pretty good. Crystal Defenders was not a classic FF (tower defense), but also had older style graphics and was unique. We just want the same feelings we had during FF4 or 6, which won't happen. When a game is truly good, like FF9, it can easily be over shadowed because it still isn't good as those we feel nostalgic toward.
