I say go for it. XII has its eccentricities but I felt it does an outstanding job. Its story is more plot focus than character driven and the pacing is off cause the game world is huge with lots of things to discover but I feel this is a nice trade off.

If you're someone who loves more story focused games and could care less about the game side as long as its not terrible, then you might have some issues with XII cause its easy to go hours without another story scene. Especially since the game let's you go almost wherever you want rather early in the story and most side-quests are made available rather early in the game.
