Yeah PoE is very good with this; I only end up killing one dragon in that game and leave all the others be.
But I agree wholeheartedly with the point of the OP. I've never understood why everything has to be about killing anything we come across. In the tabletop games that I played, which were a great many back in the day, we always at least tried to talk/negotiate.
I think it would be really awesome to be able to talk to a dragon, exchange stories with it, get advice, get some quests, become friends, maybe even become allies. And, I think this would be cool with other awesome monsters as well - like giants for example.
