X:Loved everything about it.Sad,perfect ending,made me cry.

X-2:IMO,it was a great game.Plot/Story/Character-Development was practically nonexistent but the side-missions/battle system/sheer lightheartedness of it all was kind of a break from the whole typical "Doom-and-Glooom" feel of some of the other FFs.

AC:I liked it,and i'm with ~Rikku's_Lover~,graphicwise,it was gorgeous.Some of the characters were just fan-service IMO.I liked it though.
