Best game ever

[Belugn]

I don't really label games as best, because I'm not really that involved in games to well, be able to do that, but FFXII is sure one of my favourites. It had everything I wanted from a game, being sort of a like a book, with all it's hidden mythology. I'm really into world and story creation, so FFXII was a huge inspiration, and executed BEAUTIFULLY. I'm glad you enjoy the game, and I hope you'll be doing it through it too! Just try to get your own opinion about it, that's the way to go.

I have a confession to make xD

I've only played FFX and XII, I really want to play the other games as well.

As for the 360 I must say Assasins Creed!

FFX is my big nostalgic emotional favourite, being my (late) introduction to the series, but I've played lots of older titles now, currently getting my way through FFV.
Try to get your hands on FFVI! It's in my opinion one of the most enjoyable FF games, it's got such heart and spirit, and imo one of the best FF female character. You could try finding it for the PSX i guess, but what I've seen, it's expensive. There is a really good re-release of it to the Game Boy Advance though, with a rewritten script of high quality.
