That could work... screenshots would be vastly inefficient, but saving system information into a seperate file (e.g. gameName_playerNumber.map, or whichever file extension) could work nicely. Would be more... graphical than keeping a Notepad (either the Windoze or the physical variety)archive of each game.
Thus, it becomes an individual player's option, and doesn't bog down TCP/IP, PBW, PbEM... Why didn't I see that?
Oh well.
