Final Fantasy IV hands-on at Siliconera.

"I’m sitting down to play the Final Fantasy IV demo and I’m expecting to play some part of the game I know. Maybe walking through the Cave of Mist since that’s at the very beginning of the game. The demo begins with Dark Knight Cecil and Kain making their way out of Baron castle. They meet in the center and talk. That’s right talk. Final Fantasy IV has voice acting! When they exit the castle Baron’s army greets them on their journey and all of the sudden you’re grouped with an impossible party: Dark Knight Cecil, Kain, child Rydia, Cid and Rosa."
