Much of what you described is not historical or arcade
Is there any historical data that suggest this was remotely a factor in any war in any period?No saboteurs to take down buildings and important structures,
Competent armies used a variety of methods to "spot" the enemy. Leading up to the Battle of Kircholm (1605) It was a captured soldier that revealed the size and disposition of the Polish army. In Paradox, you can set-up an espionage network. This would be much more historical without resorting to cheap arcade gimmick.no spies to help you spot an army or check their ranks or even unlock a gate,
You need a physical incarnation of a "merchant" to accumulate wealth? How is this superior to a more historical manner of using, research of a new idea, the invention of a new technology or a building of a trade network?no merchants to help accumulate wealth,
A policy would be a more historical means to promote public order. I have always thought priest "converting" the masses as an arcade-like gimmick the sooner they put an end to agents like this, the better.and no Priests to help keep public order high and put witches away (thanks for taking away Religion and Culture CA).
As I mentioned earlier, I was fine at first with Shogun using a Ninja to assassinate, but they overused agents in later titles when there are definitely better more historical options. I only hope this is a trend and not an anomaly.
You described the lack of agents as "lazy and lacking depth, but the concept of agents has always been a lazy means and a silly arcade approach to a game that claims to be historically based game. The only difference now is that instead of sending an agent across the map, a complete waste of my time, I can simply give the order and it is either done or not done.
