Though I enjoy every RPG you can throw at me, with few exceptions, I am picky when it comes to one I say I would love to play again and again.

I don't really care too much for RPGs that are short of a good plot. For it to be a good plot, I want it to be original and have many good things supporting it, such as a good cast of characters.

As for the characters I don't want them to just pop up and be playable. I like the plot to take you into the back stories of all the characters, even if just in a subplot (i.e. Vincent from FFVII).

I like battle systems to be unique. Not just X mashing like some FFs can become later on in the game. I tend to like them to be more comlicated and requiring you to think, which is why I love Final Fantasy Tactics so much.

Music is also very important to me. I find that music, and most will probably agree, can make or break a game. The music of a game can be the single thing that really gets you into the game. And when I say music, I mean music, not always some synthesized techno stuff. I loved the opening to Grandia II which had piano and violin I believe. Music can change your emotions more than what happens in the games. (SPOILER)Aerith's death wouldn't have been half as sad without the magnificent theme and you know it.

So yes, I am picky, very picky. And looking over what I had to say, one of the few games that came up to these standards for me was Final Fantasy Tactics. Though not all the characters you played as were greatly important, there were a great deal of them who were (such as Agrias, Mustadio, etc.) and even the NPCs were greatly well done in such numbers.
