As other players have said here before this game has a loyal group of players that have been here for a long time, same for me. My first age playing was the last age that ships were still needed to attack provinces on other islands.
This game needs to become more mobile friendly indeed. Still many players have trouble posting in forum when playing from mobile for instance.
I think that alone makes the game look bad to new players.
I hope the features of the own espionage page of the kingdom can be extended.
Make it show the personality, the off and def of each province. Perhaps add some more tabs on the kingdom screens. Resources, military , build, etc.
This will help a lot of monarchs/stewards running ghettoish kingdoms were more than half of the kingdom doesn't want to use outside tools.
This way it is easy to spot flaws in setups of provinces and coach them to improve and also makes warring a lot better to organize and levels the playing field a bit when warring against a kingdom that have all players using Munk, upoopu or other tools.
