This should save you a ton of time when it comes to getting the "here's looking at you kid" achievement in Civilization : Revolution. I was fed up after two days of trying to get them normally, and came up with this method. After starting this method, I was able to get my last two within fifteen minutes or so.
If you don't get the great people you need the first time, just recreate it over and over. Eventually they'll show up, and it's much faster than normal methods. :)
