The story starts off well enough, but it does meander toward the end, and FFXII has one of the poorer endings of the series. It's all the stuff in between, though, that makes FFXII a great game.
You didn't like the ending? I thought it was the most emotional scene in the entire story.
It was disappointing and didn't seem emotional at all. I guess this is because the build up to it doesn't work so well. The antagonists are just not antagonizing.
I thought in a story that felt so emotionless the ending was very emotional with Ashe's letter, Penelo fooling around with Vaan, Basch being his brother's successor, the artwork picture of Balthier and Fran in the credits apparently being together and all.
