During the development of "Kingdom Hearts II", Nomura had more creative freedom due to advances in technology. Port Royal/The Caribbean, Space Paranoids, and Pride Lands, in particular, benefited from these advances. In Port Royal and Space Paranoids, the character models were generated from live-action pictures using a new program. Nomura had wanted to include a world based on "The Lion King" in the first game, but could not since its engine could not process quadrupedal character models properly, a feature which was resolved for "Kingdom Hearts II".
