switza money survivor game

I've had requests to try to get a new season of this going. Basic rules as last time, maybe a few twists.

General idea of game:

1. Regular Survivor game with tribes, challenges and losers going to Tribal Council.
2. Instead of typical imdb Survivor challenges, everything is a bidding war. Each player begins with X dollars and for the challenges, you bid for immunity and highest combined bid by tribe wins and losers vote someone out.
3. There's also individual temptations you can bid on that can help you but won't help win immunity for your tribe.

We'll start at 20 or if sign ups die on a good cast size like 16 or 18.
