Another thing I’ve documented that some may find handy is how Sierra Knox and the ‘Global Innovation Race’ works: Miami Race Manipulation - Google Docs - e.g. when she comes off the track, what triggers exist to make her come off sooner, what triggers exist to make her stay on longer, and more.
I also respect efforts such as Hitman all dialogues project and think maybe this could help in that, as many of these NPCs and targets have dialogues on their natural cycle, in addition to the ones that only occur when you get close enough to trigger them.
