Mortal Empires is Total War’s grandest of grand campaigns: a stunningly huge global war with over 100 factions and 35 leaders duking it out over multiple continents. In terms of scale, it’s the series at its most ambitious, and its most daunting. It took me an hour of second-guessing and two false starts before I finally settled on a faction and leader. It’s excessive, really. I love it.
