Blue Magic is the most absurdly broken magic type in pretty much every game its in. Final Fantasy X was the sole exception. If Wolf thinks that it wasn't broken in FFVIII, he's never seen Quistis spam Degenerator and wipe out every enemy on the Islands Closest to Heaven and Hell before they can even move. It was useful in that game because with low HP, it was quite spammable. Also, the way the HP/Limit system worked meant that the change to White Wind's mechanics kept it just as broken as ever.

Of the main games, Final Fantasy VII has my favorite incarnation. It took knowledge and setup to get mastery of it, but you could usually pick up a decent amount of skills just by playing through and keeping it on. And you'd still find ones that were broken beyond all get out. Like Matra Magic and Aqualung.

Of the side games, I think it's most powerful in Final Fantasy Tactics Advance, where it can make your party essentially invincible forever. I adore the way Bravely Default uses the codex to tell you which monsters have Genomes you can learn.

I think Bravely Default had the right number of spells to learn, but I don't think it did as great a job of diversifying them as it could. Mostly because status moves still aren't super useful, and because few of the Genomes are magical attacks (in fact, only the Norende -aja spells are magical, all other attacking Genomes are physical).

Dissidia. Most broken ability EVER in that game.

Still, it usually does physical damage that negates defense, which can be pretty awesome if you use it against the right foes.
