My last request: North & South
http://en.wikipedia.org/wiki/North_&_South_%28video_game%29
I remember playing this on a friends Amiga back in the day. It would be nice to play the Atari version. I am a bit surprised it is not here already, as I remember it being quite a popular game back in the day.
