The only seasons yet to be released that I would buy are Africa, Marquesas, Amazon, Vanuatu, and Exile Island. I loved the cast of all those seasons. Thialand and Guatemala were too boring. And I'm not bothering to pick up Palau because I was very disappointed with how the first tribe was decimated, Ian quitting the F3 IC, and Tom winning. I didn't like Tom cause he was too strong, I root for the underdogs.
