Ooooh so many interesting ideas!
We had a similar story at one point, where the player has to pose as an acolyte and investigate the death of the former high priest, talking to several members, finding a way to enter the restricted area... After a while setting up all the triggers and conversations and scripts turned into a huge PITA - although it was quite funny to start a conversation and then walk off, having them talk to thin air
I'll see to it that our story is not too similar. Although also placing our mission in the same universe and have some familiar characters appear (or at least being mentioned) would be a nice idea.
I like stories with multiple possible endings
Looks like I have to (re)play some TDM missions then.
Mmh, we do have a library, but it is probably too small for such a degree of labyrinthinity.
