I'd like to say that FFV has always been and will always be my favorite FF ever...and believe me, I've played and own all except the original III(NOT VI), and FFXI.
What do I like about the game? First of all, the simplicity. You know when you'll level up, you can't get too lost, etc.
I absolutely love the job class system and think its the best out of any FF.
Your party is PRETTY MUCH set, so there aren't too many deaths...which is good, because you'll never have to worry about the constant person you like dying.
I find the music very catchy, and the levels appealing.
The summons are plenty and quite cool.
Oh yeah, and Gilgamesh totally kicks butt!!!
