So, now we've just talked about history and visions, I'll try to clarify a confusion about sandbox, historical events and plausibility. Europa Universalis have always been about historically plausible outcomes, as
I mentioned over six years ago , and EU4 is no different in that regard. No determenism or full sandbox will ever be in the EU series. In EU3 we scrapped historical events and added lots and lots of system and mechanics to create more plausible gameplay. While we are continuing on that concept and keep making more plausible mechanics, we are in EU4 doing something new...
We'e adding in Dynamic Historical Events. We'll have more of those than we had historical in EU2, and together with a fair amount of other planned features, this is creating an even more immersive type of gameplay, where countries feel far more unique than they did in any previous game in the series. A 'dynamic historical event', or DHE for short, is an event that has some rather rigid triggers that they feel plausible to happen with, ie, no Spanish Bankruptcy just because its a certain date, but events that tie into mechanics rather heavily.
The example I want to talk about is War of the Roses for England. At any point of time, before 1500, if England lacks an heir, then the chain for War of the Roses
can start, which creates a lot of interesting situations for the player, as well as giving unique historical immersion.
