There should be a list about the previously played games containing the parameters (seed, map size, difficulty etc.) including whether the game was won or not and possibly in how many turns.
Icing on the cake: share the parameters with others somehow so they can try to beat you.
Related suggestion i received via email: When winning/losing a game with a seed that was won before, show the "record" number of turns achieved previously.
@cyberbeat gave some input about this in #49.
