I’ve never really randomized objectives but I have assigned secret, sometimes conflicting objectives in multi-player games. I’ve use this in both French and Indian War scenarios as well as Aztec games. Usually adds a degree of suspense and variety to the game. I suppose if I was actually playing in the game, drawing the objectives out of a hat would keep me in suspense, too. I like that idea.
