This map was made as an Augustus Scenario, so it had .svx and .map file when I downloaded it. I like to play the original Caesar 3, so I played the .map file, I'm really not sure if the author meant it to be played with Augustus with .svx file.
The one I played finally resembles a campaign map, which I really like, because I had so much fun playing it.
