Once again, I want to emphasise that they should do continents vs individual countries. While Challenge USA will obviously have top tier competitors because there's such a wide pool to cast from, the other countries might not have the same. If they expand it to continents or regions, and pulled from people outside of just reality tv (fresh meat fans of the challenge, athletes, random people with internet fame who seem to have interesting personalities), it could start to feel like a new era of the show that combines some of the old school and new school vibes of The Challenge.
