Another technical GDC talk about The Sims 4. This time on how to get multiple Sims have different paths when they have the same goal (giving each other a hug) and how after the action, their paths are again different.
There is also a hint that cut-scenes may come back, Slide 58:
Dynamic Cutscene Sequencing
? Allow for in-gameplay cutscenes
? No need to interrupt in-progress behaviors
? No need to warp actors at synchronization points
? Could run in parallel to regular gameplay
These slides are of course only half the story and very technical, I really hope they will show the recordings of both GDC talks to us for free
