CG is not a problem. If you want pure visceral gameplay with zero story, then yes, FF is not for you. However, FF XII doesn't have a ton of long, long cut scenes barging in the gameplay.
Not only that, but all Square's cutscenes were not CG. Mostly they were short scenes lasting a minute or less. This game has gorgeous CG more frequently than in other Square games. The introduction of the game is fairly long, but it's not obscenely long by any standards. In fact, with the voice acting, action, and music, it's actually quite good.
Nice thing though, if you don't like cutscenes, you can skip them. So, please, more "concerns", please! I want to knock them down like bowling pins.
