Tremendous graphics and an enthralling visual style are two of the positives of this game. The thing that left a lasting impression on me was the battle system. It is superb, perhaps even the best in the series so far. Along with the Blitzball minigame which consumed many hours of my life, Final Fantasy X had some worthwhile elements that made the game worthwhile. Sadly, it is still a 'marmite' game in that you can hate some parts and love others. The voice acting on the whole is dire, even the protagonist is an embarrassment, too frustratingly useful in combat that you can't just ignore him, or his 16 year old cheerleader's voice.
In terms of the characters, the only one of the main party I liked was Auron - and not just because he is the brooding hero of the bunch! He was the only character voiced with any style or given a shred of sophistication. Even the matriarchal figure in your party lacked any sense of intelligence and even seemed childish at times.
There is a monster breeding addition that was obviously a desperate attempt to make the game appear longer and let it claim a few more gameplay hours. The final boss follows on from the trend of Final Fantasy IX in being extremely easy, even if you hadn't levelled up your characters, and the fight lacks any real emotion. Even the soundtrack, usually a sure fire hit from a final fantasy game, was weak.
The ending was ambiguous and only served to spawn a god awful sequel about a bunch of characters they failed to make us care about the first time around. I always got the impression that this would have been a better stand alone game rather than one of the proper Final Fantasy series. I don't really know why. Final Fantasy VII revolutionised the genre when it appeared on the new PlayStation console. Final Fantasy X had the chance to capture us all again on new hardware, but it completely failed to deliver the motherload.
