Yeah its the wee things that make this. I'd being trying to control the whole of Ireland to start with. Got my son a wife with the "lustful" trait so he'd hopefully have a rake of children, he had a son, who I started being a guardian too, this seemed to piss my son off without me actually realising though as his opinion of me rocketed right down.
Got a message telling me about going into a pub, then the whole pub exploding and me dying Took control of the son, hovered over the previous ruler and its "suspicious circumstances" while my son now has the "kinslayer" trait.....
Son was then assassinated by the allies I'd made when I was the dad, in a cracking twist.
Going to take a lot of plays before I learn to cover every angle I reckon.
