Glad that you liked it.
Yeah, some of the other adventures are a little more clear that some NPCs will be difficult to persuade to do certain things compared to others. This one does not really have that for some reason. More physical challenges are mostly left for the referee to decide: it is difficult to know if a given PC should be able to spoof a biometric lock or not. Will have to think about how to flag that sort of thing more clearly.
As for the other adventures, it was always the intent to have a nice big stable of NPCs with some cross-connections that could start to snowball into future adventures as the PCs start wandering around. A big party makes a lot of sense for seeding those links to me.
