True that... but then again, we can only compare them to the games of their own calibur in order to proporly gauge their worth.
My whole premise is that, to use an analogy, you can't compare a quarter pounder to a steak. I mean, yeah, the burger is nice and all, but in the end you know that it just doesn't compare to a good steak, so you're left trying to decide what kind of steak you like. (Ok, as you've probably guessed, I was hungry - VERY HUNGRY - when I wrote this.)
ANYWAY... the same is true for the ff series compared to other games. Even though... oh, lets pick on Illusion of Gaia. Even though Illusion of Gaia was a fine game in its own right, it simply doesn't compare to most of the games in the FF series, and the ones it does compare to, most will agree, it compares to poorly. Its not that its a bad game, it simply can't match the firepower of final fantasy.
I, myself, chose FFMQ for the worst ff game. Not that it was actually a terrible game, in fact I rather enjoyed most of it, excepting the end - most of you are familliar with my rant about the final boss by now. But it had corny moments galore, and the two person party limit, the somewhat retarded AI, and the return to single spell based magic limitations was a little... repelling. Still a decent game... but a horrible Final Fantasy.
