Mike could've offered 3 players 1200 and 1 player $1 to make the most of it.  There's also the problem that each person is "famous" and cannot hide in anonymity if they did "steal" the money.  Would be interesting to invite at least one person that has "notoriety" and be in character for them to do something villainous.,(reply>), More interesting would have been to offer 3 players $1500 and the fourth $0 - the three are each $300 better off than they would have been with a 5-way split, and each getting the same as Mike...
