Okay, so, we slept on this a little - in part because the first portion, the Epic BattleLore expansion that'll open the game up to 6 players at a time, was expected. But this Call to Arms business is entirely intriguing, offering an alternate card-based army deployment system. It'll hit in April for $20, whereas the Epic stuff will hit this month online, so register those back-of-the-booklet codes if you haven't.
