Yeah, I agree with the goal. More dynamic worlds could be very interesting. However, I don't really think this is a step in that direction. The implementation in Kingmaker is simply the exact same timers we've had since the dawn of gaming. It's never been hard to implement, or a matter of technology; it's just a design choice by the developers.A world that really moves on while you experience the story in that world is certainly a nice goal to look forward to.
But honestly, I think you need a game master to do that in an enjoyable way. Or an AI that is capable of replacing that game master. I think the Sui Generis kickstarter was partly suggesting to go into that direction. Too early.
Maybe in 20 years.
Proper AI development is probably the only way to go beyond the dynamic worlds of The Witcher 3, Gothic 2, GTA5 and so on, which is bound to happen, but we're not there just yet.
