I like those card options. I was thinking on how one to use the card driven game machanic for A&A.
I’m not sure if anyone here has played a CDG before like “Paths of Glory WW1”, “Barbarosa to Berlin WW2”, “The Napoleonic wars” or “Sword of Rome”. But, everthing you do is based on the cards in your hand. If you want to move a unit you have to use a card. When you battle, cards in your hand may give you an advantage. There are event cards that reflect what happened in history but the time there are played may not be historical. There are respond cards that negate or cancel a previous played card.
Cards act as resources and you have to manage them well, because, once you are out of them you may be in trouble. The geneal idea is that you can’t do everything you want in one turn. Like, “Do I activate this army to attack a key city or do I use the event to gain an advantage the next turn”. Things like that.
I’ll post some additional ideas later.
