Another idea

The players are placed in the middle of Asia and it’s a five day challenge the timer ticking down like a bomb

Much like tag you will need to pay for your transportation but in miles, not vehicle. As at the beginning of the game, all players will be given a car.

Your goal ? Get as far away as you can.

The player (or team) farthest away from the start wins.

If a player is able to drive to either the west coast of Asia (this might not be possible due to political reasons in China) or east coast of Europe, then they will be able to do challenges for a flight ( since it’s by mile air travel across the Atlantic would be like five challenges)

Just an idea, let me know if any questions .
