Yes, in my Eiperote campaign, Phyrrus and the Makedonian King, whose name I forgot already , engaged in a melee, fighting each other and finally killing each other.

It was great. My Phyrrus died, but took the Makedonian king with him, since that day, Ptolemaio Aikades, or whatever is his name, swore revenge and hunted Makedonians to the last man walking on Earth, much like Alexander and Darius. I felt great pleasure in destroying Makedon and exterminating their population. Lots of fun.
