Anyways, how about another game option that allows the game creater to select different numbers of bonus armies placed on territories you control that match cards you trade in?
BONUS TERRITORY CARD ARMIES:
(_) 0 (none)
(_) 1
(*) 2 (default)
(_) 3
(_) 4
(_) 5
(_) 6
(_) 1d6 (random each time: between 1 and 6)
(_) d6-d6 (random each time: roll two dice; subtract lowest from highest; between 0 and 5)
(_) + (escalating: zero for first card traded in representing a territory owned by the trading player, one for second, two for third, three for fourth, four for fifth, five for sixth, and so on,
(_) X (other?)
I especially like the idea of the escalating territory bonus armies, especially in junction with a standard escalating trade in value game. For example:
