Thanks for this walkthrough.
I'm doing investments after the reunion and am curious: The walkthrough includes Beautification (5k) and Cache Excavation (10k). Cancelling either of those would permit obtaining the Ardford Restaurant which I would like to get for the extra income and side quest.
I think I understand the reasoning behind the Cache since it's irreplaceable character power, though I'm happy to sacrifice that and spend some Sx on equipment (if I could buy the Cache with Sx I'd do it in a shot). I don't understand the beautification project - is the extra early Janine RP needed for a check?
