I just filled out the closed beta form earlier today and got curious what everybody entered as their favourite feature from a PDS game.
I said AE from EU4, as it fulfils its purpose of limiting player expansion, the basics of how it works are clear (any listed nation in the peace screen tooltip can join a coalition against you), but a skilful player can go into more depth to make the most of it (e.g. truce cycling and spreading expansion out).
P.S. I'm posting here as it's inspired from the CK3 beta, but might be too broad a question for here.
