FFX was the first FF game I didn't buy, though I rented it twice. I even dodged the lightning 200 times for Lulu's weapon.
It wasn't the first one I didn't like though. I hated 7, liked 8, and 9 was utterly forgettable to me though I liked Vivi and Beatrix.
And I bought and liked FFX-2 for some reason even though I barely even finished it.
So of all the games in their catalogue they choose FFX, and I am not excited. I mean I'd love HD Lulu, Rikku, and Auron as I used them exclusively, but the reason I didn't buy the game is that it just had zero replayability to me. Once you have gone from point A to B and dinked around getting weapons thats pretty much it. That I hated blitzball, the spheregrid, the storyline, and most of the characters also didn't help.
I want, possibly more than anything else from SE, is an HD remake of Vagrant Story. Second would be a new FF Tactics, or a 3DS port of the original.
