I think it would be great if a end of game summary was added when the game ends. Especially via assassination.
Even something as simple as a time log of changes I made to the game. What taxes i changed, new ideas implemented at what points. Even better would be the ability to historically look back though a history view of each quarter as the changes happen.
I know I can do all this as I go but I would like to be able to study data as a whole after the fact if possible.
Also it would make it easier when explaining the game to friends what exactly happened if i had a complete playbyplay :D.
