Both of them unique in their own way. Wipeout involves participants involved in some crazy stunts much more intense than Survivor or Fear Factor.
And I’ survived a Japanese Game Show is another very interesting game show that involves participants flown to Tokyo as Gamers in a crazy Japanese show. But I have my own doubt if it's really a Japanese game or just a show customized for American audience.
It will interesting to see how the Indian version will be ?!
