Seriously? You are still asking that? I would have sat down beside you and tell you about
the Lord Jesus Christ’s love Eorzea but I am planning to hit the sack soon. Luckily for you the kind folks at NeoGaf made a visual compilation of the MMO (with sound, text, animation and pictures) for curious people like you. If you wondering what’s so great about the game and whether it is a game for you; do check it out HERE. Seriously do check it out, it’s awesome. Even if you are not interested just go and take the look of the visuals.
