I definitely prefer the idea that Harry is a ghost that hasn't realized he's dead yet over all of this being Cheryl's delusional imagination to be honest...
Yeah when I played this years ago I hd taken it that she had actually manifested the ghost of Harry, because of the therapy. That she was creating the nightmare scenarios for his ghost but that the event itself was actually happening otherwise, that also has some weird plotholes around the other people and how they are perceiving Harry when he comes and goes into and out of reality, but at least in that concept there is actually something happening, not just the tired old all in your head cliché, second only to the busted ass it was all just a dream.
Listening to Lisa's voice acting again I just realized that she did the VA for Phi from VLR. And Aigis from P3... And Nanako from P4. I thought she sounded familiar...
I am a little disappointed that sgf isn't looking for more of the differences in the phone calls and ghost messages during this second playthrough. I imagine that's where a lot of the actual changes based on your points are, as the short audio and text messages could be pretty easily swapped out without changing the main structure of the game and story. I get it though; as oddly compelling as this game is, the act of actually _playing_ it doesn't seem all that enjoyable, so he probably just wants to get through this run as smoothly and quickly as possible. Oh well, I guess I'll just have to look into what's different there in my own time.
I think all of the voicemails on the path to the high school were slightly different. It is interesting just how many there are given how loose and roughly-implemented the psychology points system is in general.
