If the next game doesn't:
-Let the characters talk naturally
-Let jokes come with buildup instead of forcing them to be funny
-Not make everyone talk all "epic" and "mystical" and shit
-Stop using 1920's style cartoon sound effects
-Use Times New Roman with 12-point font
-Use MLA format
-CITE THE DISNEY WORLDS' FUCKING SOURCE MATERIAL
Then there's no need for improvement whatsoever.
(Don't ask about those last three points, I'm an essay writer.)
