Never said it was climbing Everest, but come on - they have an achievement for promoting a unit. How about a little reference to the fall of Rome?
BTW, it was my first time doing it in two years of playing. I like using random AI's in my games, and Rome has turned up only three times, give or take. In one of those appearances, he DOW'd me (I was playing Bismarck), and it turned into a 200+ turn slug-fest where Rome finally cried uncle - and I still didn't get to capture his capitol.
