This game holds a lot of my personal awards: favorite JRPG, favorite console RPG, favorite story and favorite Final Fantasy game.
I know some FF VII fans out there just revoked my "RPG Fan" membership card, but that's what I feel.
First, the mechanics of this game are rock solid. Turn-based combat and an incredibly deep character advancement system that allows you to really build a party to your specifications.
Need another healer? Another black mage? More warriors? You can do it.
This game also has a ton of content, with optional dungeons, weapons and quests to undertake. After playing through once in a fairly impatient, straight-line manner, I was amazed at how much story I had skipped.
I also love the characters, the voice acting and the story. On that last front, I'll just say that this game pulls off something very few video games of any type do: it had a story twist I didn't see coming.
One last, highly personal point, this game single handedly made my 12 year old niece and all her friends into RPG fans. If you ever wondered why Final Fantasy X-2 was a little girly, with the J-Pop Charlie's Angels vibe, it might just be because there are more groups of girls like my niece and her friends in the world, who run around pretending to be Yuna, Rikku and Paine.
