I'm pretty sure this is how the risk board game is played but I'm not sure, but anyway, how about as a new option, not replacing escalating, how about this card option:It's like escalating, but whenever someone turns in a card set, they get the extra armies every turn, and Until someone else turns in a card set, everyone else gets a 4 extra armies every turn as well. Next time someone turns in a set, the same thing happens but each player gets 6 and so on. Ex.
Randy turns in a card set worth 4 armies
Randy gains for armies for 12 territories etc.
Buddy gains 4 armies for a card set
Buddy gains 4 armies for 12 territories etc.
this continues with card sets worth the escalating amount
I'm sorry if I didn't explain it properly, so pls ask questions if u have any
