Ruler names and cabinets, i dont care if it has to be even fantasy. This is the only game that hasn't got ruler names and I think its time that you add it.
It would be cool if you had the ruler names and cabinets like in HOI3, that system suits the best for this period. Also the elections would be more fun, usurpation of the thrones, exile of the monarch family, establishing republic,
assasinations of the presidents or ministers, communist revolution, etc.. All those kind of things could improve this game even better.
