What do you think about a character creator with an East Asian theme? Imagine samurais, arquebusiers (Japanese gunners), Mongol cavalry, and characters from China (Ming and Qing dynasties) and Korea (Joseon dynasty)—I think it would look really cool. Although not about pixel art, there are some games that come to mind as great references, like "Imjinrok 2+" and "Gersang."
