You're right however I can tell you that JsDeacon as far as I can tell, he was never very explicit and in his WT he always just gave directions, it's up to you to save and do the various trials until you succeed, this was never an easy game, maybe only at the beginning.
I only remember to find the little hidden scenes, it took me forever, but maybe that's also the beauty of an RPGM.
At least you know who you have to ask for the biscuits, the dildo and the stethoscope. For example, did you know that the dog scene with the vet changes, even if only slightly, depending on the time you go there? But this is not written on the WT
Oh don't get me wrong, I do believe in the exploration and solving problems on your own. I've played Manilla Shaw, saving after each decision or scene to try everything to get different scenes and endings over 7 different playthroughs and love it. I did the same when playing this game.
My only point about that was that so many posts and this WT are telling people what they need to do in pieces, most of which are entirely wrong, and misleading them. Reading all of these and trying everything for hours to get just one treat and never getting anywhere was so frustrating I gave up and just loaded save slot 39.
I was one that tried all of this and never knew that if you used the dog dildo too many times it would glitch the entire quest or waiting too long to start it would also glitch it.
Like my other post above about TheLecher saying it has been repeatedly answered and his rant trying to justify why he was not answering, it wasn't answered anywhere in 226 pages, I don't want to mislead people who are asking for help by letting them think these answers are right or complete. I know that because I spent over an hour searching every post about this topic and then trying to figure out which ones were right, wrong or partial and how to piece them together.
With that I believe that people should visit the guy in the part early on in the game. If they can get the dog dildo and have been allowed in the abandoned subway to find the stray dog, to use the dildo a few times and trying to talk to the old vet each day after in the morning or during lunch (you can still visit him and have lunch with Andy) until you get it. And make sure to get the stethescope as soon as it lets you get it.
That was my takeaway from over 20 pages of comments and the walkthrough. It's not complete I know, just a basic guidline.
