[Irouleguy] You don't try to make people predict the future; you have x quickfire slots and y slow burner slots. If a quickfire game ends you can only replace it with another quickfire game; if a slow burner ends, it can only be replaced with another slow burner. If one slot of each type chances to be available at the same time, then you get a choice. After all, an /unsuccessful/ slow burner will still face the chop relatively quickly; it's only the successful slow burners that will hang around.
BTW I too have a game suggestion: Hide and Seek. This idea was inspired by listening to an old ISIHAC episode where the teams gave it ago. Seemed to work all right.
