4. Draw the private objectives after you are done placing the initial set of control markers. This way, you can avoid the situation of having achieved half or more of the private objective as part of the initial set up.

Also, I'm half tempted to buy a second set in order to get duplicate secret objectives (as well as extra scout and shugenja cards, for 7 player variants, and a spare board) so that multiple people could have THE SAME secret objective. Now wouldn't that make for some viscous conflict!?
