I wouldn't say they're better than all the rest combined; I'd really have to think hard about that even if it was Nintendo. They are awesome, though they have been bugging me lately in some ways.
FFTA2's storyline was the exact same as FFTA. And lame.
All the FF7's aside from Crisis Core were crap and unnecessary.
NO ORIGINAL MUSIC in FFXII-2. (Aside from...1 song, maybe?)
And they should be ASHAMED for C&D-ing Crimson Echoes on it's last month of development, when they have shown no initiative to make Chrono Break.
