G4 has an article discussing some of the hits and misses of FF innovation. According to them:

Hits: I, IV, VII, X

Misses: II, VIII, XIII, XIV

I actually agree with a lot of it, despite not liking X overall. The selection of what games they discussed is a bit questionable, though I suppose volume was a concern. For example, XII's combat and gambit system was very new to the series, as was the game's plot and development. I'm not sure whether to classify that as a "hit" or "miss," because it definitely had both positives and negatives.

What do you think? Any other major hits/misses in the series?
