Final Fantasy is pretty cool. However, there are long drawn out mellow dramatic scenes throughout the game which you can't skip for some reason. It gets really annoying when you've got to fight a boss, and you have to sit through 5 minutes of dialogue everytime you have to re-fight him.
It is also turn based fighting, so if you're not into that, you may not like it as much. I am more into real time action, so it took some getting used to. It is a beautiful game though. If you've seen the Final Fantasy movie, the rendered cut scenes in the game are just as well done.
However, I don't think you should go out and buy a PS2. You should just play more Aces High. Just tell yourself, "one more sortie..."
