When the talks are Tinto #20!
Johnan goes more into depth about tech and institutions. He also mentions national ideas and idea groups, and what is gonna replace them in Project Caesar.
It's a pretty interesting system they are developing. It's sort of a misson tree at first glance, but actually quite different as it is based on techs and institutions. Most of it is shared between all nations but the equivalent of unique NI's is that some nations have unique advancements and paths for them.
In particular, this system allows for Paradox to fix the problem of nations which historically only got strong in the late-game period of the history the game is based on being a-historically strong in the early game and strong early game nations which historically had skill issues and fell off staying strong and never collapsing or facing issues. This means no more stupid strong military Prussia in 1510 goosestepping through north Germany like Frederik the Great had already come through and done his things (when historically they were just a backwater barely worth the marsh they were in vs. when they actually built up and geared and trained towards being a military power) but also no more having to buff the shit out of the early game nations like Ottos and Oirat and then having to come up with ways to have them debuffed as time goes on to keep a total snowball from happening every game.
