It was the 90's in general. In America we got IV, VI,VII, VIII, IX, FFTactics, Chrono Trigger/Cross, Mario RPG all within one decade, and I've heard people debate why each or any of the titles are the best of the series. After the 2000's we've gotten X, XII, XIII and Kingdom Hearts, and only two of those titles have been as popular as any of the ones from the 90's. Quality has suffered over the years.
