There have been some pretty impressively developed games on my server recently, especially with the pak.Britain players. I am keeping an archive of these savegames online for anyone who's interested in viewing them. This can be found here:

I'm going to start saving screenshots of the map at the start/end of the game, as well as details of the pakset/game version as well. I've been very impressed by some of the networks people have set up :)
