Struggle of Empires is my favorite Wallace game. But even better (so I guess that makes it my favorite) is the retheme of Struggle that Wallace did for the rerelease of Conquest of the Empire. It streamlined a lot of fiddly bits and was basically Struggle of Empires 2.0 super elegant, super fun. One of my all time favorites.
Paul Beakley if you don’t know that game, you should.
