Shorter Save File Name
Shorter Save File Name. Only contains civilization name and turn number, instead of leader name, turn number and fake calendar year.
I always find it hard to name the save file during the game, especially when you want to add additional info about the state of the game, like received a relic from goody hut, researched Industrialization tech, etc. The default save file name is too long and you have to remove the trailing "years" most of the time. Even with that, the save file name will still be long if the leader has a long name. Hence I changed the default to only contains the civilization name and turn instead.
