Yeah, the problem I have with that approach is that it’s obvious to the players that they didn’t get the entire scene. (And it also becomes obvious exactly when they gain whatever it takes to unlock the parts of the scene they missed out on. “Visiting this location gave us card 3, wasn’t there some place where we needed card 3?”). Or at least that’s been our experience with Time Stories, which uses a similar system.
So rather than being a reward for the players figuring out some part of the mystery (which is the experience I want), it just adds some hidden dependencies to which order you need to do things in.
