We're about halfway through the Core campaign, playing IA for the first time. However, I'm enjoying it so much I picked up Twin Shadows last week. Should I go ahead and include the various items (upgrade cards, supply cards, Heavy stormtroopers) in the current campaign, or would it be better to wait until we actually get to that campaign?
I feel like adding them would be fun, since it would be new stuff to see, whether new equipment for them to buy, or new enemies for them to kill. Otoh, perhaps it would make Twin Shadows less exciting when we finally get to it. Thoughts?
