Just popped in the International version on PCSX2 with 4x uprendering and 4x MSAA to compare with the posted screenshots.
There's significant improvement in the game models used, you can actually see the individual fingers on Yuna's ingame (not cutscene) model in the posted screenshots. The PS2 model only had crude rectangles to represent her fingers.
EDIT:- What Dantis said and posted, good show ol chap.
One of the best FFs I've played on the console, great direction and character motivations plus a memorable plot and ending.
The Sphere Grid has yet to beaten in terms of completely offering full customization for your characters in ANY FF game. Not even the License Grid in vanilla FFXII can boast such flexibility, the Crystarium in XIII is also a pale imitation of the SG in X. (Remove Spheres and +4 Spheres to all stats)
The joy of making my characters into Demigods to take on the Dark Aeons in X International has never been surpassed in any FF since. 250+ to all stats, 80000+ HP on all chars, + crafting the Best Armor (Break HP Limit, Auto Life, Auto Phoenix, Ribbon) + getting the Best weapons.. Also the FF with the greatest Damage capable with a single hit (99999 damage).
I could go on all day why this is best FF.
