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.
