There’s even more land in Gloria Victis now, enough space that everyone has all the reason in the world to spread out and never come into conflict at all. But all that new land brings with it six new settlements to capture including two massive castles, because the fact that there can be peace in no way indicates that there will. So realistically, more land just means more stuff to fight over. If you look closely and have a certain degree of cynicism about human nature, there’s a lesson there.
If you’re not interested in that side of things, though, perhaps you’ll get a kick out of searching for various hidden treasures scattered throughout the map. The more you loot, the better stuff you get, leading you on a merry chase across the world to find all of these secret caches wherever they may be tucked. Of course, that might be a problem if some of those treasures are tucked in hostile territory… so maybe there’s a good reason to fight over that new land after all.
