Since Civ 1, I have always enjoyed a game score and being comapred to Dan Quayle or Abraham Lincon. For end game I think some stat for each map win or lose, eh, ok lose. But seeing best score per map would be very cool. But I usually DOOM my end games so if you did implement something like that the stat should be kept, maybe to a max of 10 games per map.
And by the way havent run into Dan Quayle or Abraham Lincon yet, or Trump lol. But the character names is a gem.
