I was curious to know which civs belonged to which category for the purposes of selecting Random Offensive| The main surprise to me, and possibly to some of you all as well, is that some of the civs fall into more than 1 category. For that reason, it's possible that my list is incomplete, although for various reasons which I won't go into at the moment I believe it probably is complete. Here are my results for each category. For the civs which belong to more than 1, I added a letter in parentheses to indicate the other category they belong to. Hope this is helpful, or at least mildly interesting.
