“With CastleVille, we set out to develop a fun and social experience that delivers and improves upon all the innovative social and emotional elements our players love,” Zynga Dallas creative director Bill Jackson said.

“We also wanted to bring a higher level of production quality to the ‘Ville’ franchise — from the stunning scenery and magnificent castles, to the playful characters, beautiful music and deep narrative. We poured our passion for ‘play’ and ‘social’ into every detail.”
