For the game, I have an idea.
If we do the bet idea, everyone could put in $1 to $10 into a Paypal account, this being optional, but the winner would take all. People who donate and win would get 100% of the money. If you didn't donate, you get 50 to 75% of the money and the rest goes to the second longest lasting person.
The second idea, the winner would get $10 amount of Steam games from me.
Anyways, if a lot of people want to play, we could get a list going.
