The map generation depends on the start system date and time of the main program.

I figured out that you can get to play the same map when you you can set date and time in a batch script before calling civ.. However you need to be precise with the screen, sound and mouse settings as this screen - the RNG seed is chosen by your date & time just after you do that. After a bit of training, I can get the same seed pretty reliably this way.

Are we going to allow setting this in the leaderboard? It's not something you can easily detect if we disallow it.
