How come the AGCEEP isn only about adding and modifying events?
As the creators of this project came to realize, modifying only events, limited the amount of historical accuracy they could induce. Additionally, we realized that not all of Paradox’s setups were historically accurate, and so it would have been nonsensical to ignore those inaccuracies while trying to make the game more accurate through events. Thus, the scope of the AGCEEP has come to encompass almost everything including scenario setup, cultures, new countries, modified religion and trade goods values. This is all done in order to create a more historically accurate and enjoyable game.
