World Showcase is about the history, culture, traditions, foods, architecture, art, and products of countries around the world.
I would like to see new countries and new attractions in World Showcase, but I would hate to see World Showcase become a glorified Six Flags type of park, with thrill rides "themed" to various countries. It's one thing to have family rides with minor thrill elements, such as the ride in Norway. It would be quite another thing to put a steel roller coaster inside a Mt. Fuji structure, with vehicles that look like bobsleds. Although the sport of bobsledding is now global, it's not representative of Japanese tradition. A Mt. Fuji bobsled ride would say nothing about Japan.
