Generally speaking and primarily from a personal perspective, I find the coolest FMVs to be battle sequences across the FF board. Otherwise those that introduce new characters, monsters, summons, vehicles, or some cool new item tend to be well done also.
Has anyone here ever tried playing the online card game Knights of the Crystals? I tried it months ago. It was okay. I don't much approve games run though social networks like Facebook because they require interaction from other gamers which it seems you never get. Sure, if they know you play, they'll friend you, but then they don't ever actually do anything to help you. Useless.
