Complete online multiplayer game of the outback scenario. I don't play multiplayer, so I basically ignored it for years. But turns out that you can set up an internet game but leave all your opponents as AI and you still get the achievement.What was the last one you needed? I why did it take so long?
The previous two were much more work - I needed several attempts to get a sufficiently lethal Vesuvius (if Vesuvius is mostly surrounded by mountains, it won't kill enough people, but I didn't know that until I'd poured many hours into a game), and it took me quite a few tries to get the highest rank at deity in the conquests of Alexander scenario.
