I decapitate everyone these days. What difference does it make? All the lords age out and die, the AI makes one huge kingdom, you can't marry off your family, atm you can't even choose your kid as your heir, when you could choose your kid you couldn't get married so the line ends, the mercs leaders all either get killed or age out and you can't hire them, the AI loves non stop war with you, the Kids all have stats that , well, blow chunks, so yeah, I just play to crush.
