I know many people are pretty gung-ho about playing with the map that you're dealt and not re-rolling, but let's face it; we all have more fun on these exceptionally good starts.
As such, we should start a new thread with uploads of great maps. I know I've had tons of fun on some of the maps where I got a lucky start, I'd love to share those experiences with the community and enjoy theirs as well. If we do so, I think there's a way to save the map and not the game, which (may?) allow you to change difficulty level, settings, civ, etc. But I'm not sure if there's a way to do that AND have the starting location be the same.
