VIII will always be my favourite. XIII was possibly one of the worst games i've ever played. For a game in this age of gaming to be completely linear is a crime and no downtime at all, no shops or cities to visit like the other games. It was just run forward, fight, continue, fight, continue, cut scene, cut scene, cutscene, fight, cutscene, run, fight, run, fight, fight, boss fight, cut scene x6 etc etc etc. And the best bit was after about 12 hours of this someone said to me, "ah don't worry, it really opens up after about 20 hours in". It doesn't.
